salting out isopropyl alcohol

Moreover, the technique can be easily adapted to automated systems. When TBP is used as extractant to extract rare earths, the effect of salting-out agent is obvious. You're asking if it will remove water from the methanol in vodka - so you can mix it with camphor, ammonium chloride, potassium nitrate, and WATER. Only speculation from a hobby chemist though. The instructions suggest using "Non-iodized salt", which is just pure sodium chloride or table salt. The common choices of salting-out agents used in electrolytes are magnesium chloride, calcium chloride as well as magnesium acetate. I can currently get 99.99... technical grade isopropyl by the drum for roughly 7 cents an ounce(volume). The salting-out efficiency of mixed aminocarboxylato Co(III) complexes obtained on different adsorbents shows the sorbent precipitation in the order (with small discrepancies) polyacrylonitrile>cellulose>silica gel. Pour salt and rubbing alcohol into the bags until the bowl and downstem are fully submerged. Subsequently, the emulsion is diluted in adequate volume of water to enrich the diffusion of solvent into aqueous phase, decreasing the ionic strength in the electrolyte. 7 weeks ago, Silica won't react with IPA but it will absorb both water and the IPA, Reply Though it dries quickly, spraying it on upholstered furniture, carpets, fabrics, clothing, and mattresses creates a … Seems to me table salt is the better solution (no pun intended). ‰Label pop-top squeeze bottles “alcohol, 90%” or with what percent you use. 12 years ago DNA Extraction Buffer But it's so much more fun to make it yourself. The separated organic phase typically contains little water or salt, but if beneficial, the salt identity or concentration can be varied to optimize the composition of the organic solvent-rich phase. 7.3). The functions of the salting-out agent are as follows: ① The hydration function of the salting-out agents attracts one part of water molecule to reduce free water molecule in the system, which increases the activity of the extracted species to increase the distribution ratio; ② in some system, when the anion of the salting-out agent is the same as that of the extracted species, the addition of salting-out agent equals to the increase of the concentration of the extracted species. Then just distillate the mixture and you will obtain pure isopropyl alcohol. The common experimental set up consists of two steps. In general terms, salting out is the phenomenon observed when the solubility of a nonelectrolyte compound in water decreases with an increase in the concentration of a salt. In other applications the salt residue may not be desired. on Introduction. Once the bowl is filled with isopropyl I place the filled bowl in the ice cube tray and let it sit while the alcohol and salt draw out the tars and oils. Isopropyl alcohol is most I need pure ethanol for making a Fitzroy Storm Glass. Fill a receiving bottle with the turkey baster Isopropyl contents. Isopropyl alcohol melts ice in a similar way as salt. The high salt and organic solvent concentration typically employed effectively precipitate proteins in biological fluids prior to phase separation. The diagram below illustrates the required components for such a still. For stone and ceramic pipes, it’s OK to soak the cotton swabs or pipe cleaners in isopropyl alcohol first. Proteins may then exhibit hydrophobic interactions, aggregate and precipitate from solution. A 55 gallon drum contains 7040 fl oz which would last the every weekedn backpacker about 18.3 years and since the price of Isopropyl has increased by 50% in the last year buying a whole drum now might actually pay off down the road. Effect of Salting-Out Agent on TBP Extraction of Ce and Pr [2] (0.42 mol/L of TBP, 4.5 g/L of CeO2, and 5.8 g/L of Pr6O11). Use in an alcohol stove, lamp, torch, etc. Protein precipitates left in the salt solution can remain stable for years, protected from proteolysis and bacterial contamination by the high salt concentrations. 7.2. For practical applications, only salt addition and to a lesser extent sucrose addition are important. Particle formation efficiency dropped when pH was reduced below pH 6, and particles clustered and could not be redispersed. Precipitation or ‘salting-out’ is a relatively inexpensive way to concentrate and purify molecules, including proteins. • Use non-iodized table salt or laboratory-grade sodium chloride. In this preparation, polymer and drug are dissolved in water soluble solvent such as acetone, ethanol, and methanol whereas aqueous medium contains gel with stabilizer and high concentration of salting-out agent. on Introduction, Reply Table 2.65. Many protein characteristics, such as size, shape, and charge together determine the salt concentration necessary to precipitate a protein. Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.. Isopropyl alcohol may cause burning, stinging, or a cold feeling where the medicine is applied. excess salt will settle to the bottom in a brine layer and nearly pure isopropyl alcohol will separate above. Keemi Lim, Zuratul A.A. Hamid, in Applications of Nanocomposite Materials in Drug Delivery, 2018. Isopropyl alcohol, also called 2-propanol, one of the most common members of the alcohol family of organic compounds. It is widely used in medicine as a topical application. Isopropyl alcohol side effects. I tried this just there but could not see any layers. Using Epsom or rock salt in addition to iso is also a great way to safely clean a pipe or bong. The solution is homogeneous and yellow. Figure 4.3. Use the turkey baster to extract the top layer, which will be the Isopropyl alcohol. this process is called salting out. Colin F. Poole, in Liquid-Phase Extraction, 2020. Another thing that happens when you mix you isopropyl alcohol and water together is a solution with a boiling point of 80.37 0 C. Isopropyl alcohol boils at 82.6 0 C while the water boils at 100 0 C. The solution to this characteristic is called azeotrope. There is a low variation in salting-out temperatures ranging between 0°C and 30°C. 6 years ago Moreover, an increase of temperature is not needed consequently may be useful when heat sensitive substances have to be processes [36]. It can be seen from these two tables that the salting-out agent influences the distribution ratio D and separation factor β. // So you could dry over a salt, then distill to be sure that there were no particulates in the liquid.$\endgroup$– MaxWMar 13 at 19:48 1 It employs the spontaneous formation of a biphasic system and simultaneous extraction of target compounds into the separated organic solvent-rich phase. I found an experiment online that somehow used silica in a distillation column to remove the water. The organic solvent-rich phase is often relatively clean avoiding the need for subsequent sample cleanup with the majority of the salts, particle residues, and polar matrix components retained in the aqueous phase. The current title of "Salting out isopropyl alcohol" is uncomfortable. Before you reach for rubbing alcohol from your medicine cabinet, it’s important to first understand the science behind this ingredient.Isopropyl is the technical term for alcohol. Step 1: Take a bowl and add isopropyl alcohol followed by two tablespoons of salt. ‰Fill pop-top squeeze bottle with about ½ cup of alcohol. Place jar on a level surface long enough for the alcohol and salt water to separate (15 to 30 minutes). Whichever you use, make sure it is ice cold by placing in an ice-water bath or in the freezer. Phase separation can be induced by a change in temperature, ion-pair formation, the addition of a third solvent, the addition of sucrose, or the addition of an inorganic salt. By continuing you agree to the use of cookies. As a result, the alcohol becomes immiscible with water and starts to form a separate layer. If you camp every weekend this is no more than a 32 fl oz bottle of fuel per month. This approach is useful if, eg, active enzymes are the subject of profiling. Otherwise I would research how its manufactured on a larger scale. Various peptides are nanoencapsulated on different nanoparticulate systems using this technique (Malik et al., 2007). The alcohol in vodka is ethanol. (b) Silk microsphere formed by the addition of 1.25 M potassium phosphate; pH 8; silk concentration 0.5%. Salting-out agent is the main parameter that influences neutral phosphorus-oxygen extractants on the extractability, since the salting-out agents can dissolve in water easily, and is not extracted and complexed with metal ions. add an excess of table salt to 70 % or 91 % isopropyl alcohol, shake for a minute, and let rest. Prepare a large test tube with 10 mL ethanol, 10 mL water, a few drops of bromothymol blue indicator and one drop of 1 M HCl. Unlike ethanol or methanol, isopropyl alcohol is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride. Salting out isopropyl alcohol I read on its wiki page that isopropyl alcohol is far less soluble in saline water than pure water and will form its own layer when salt is added to a concentrated IPA solution. Silica gel>alumina>cellulose>polyacrylonitrile>Sephadex = polyamide. The HPTLC results of rare earth–tetraphenylporphine complexes show an increase in RF values in the order of the atomic number on NH2-bonded silica plates and a reverse trend, i.e. If so, it wouldn't work at all. It was originally utilized in the early 1970s to enhance the selectivity of instrumental methods for metal analysis, but within a decade, it was being employed for the isolation of organic compounds and, more recently, has emerged as a popular option for automated high-throughput analysis of pharmaceutical compounds in biological fluids. Since the distribution ratio is proportional to the third power of the concentration of its anion, the distribution ratio can be increased with the increase of the anion concentration; ③ salting-out agent can reduce the dielectric constant of aqueous phase to depress the polymerization of the metal ions to beneficially form the extraction species and hence increase the D value. Salting out is a spontaneous process when the appropriate concentration of the salt is reached in solution. The solubility of components and critical phenomena in a ternary system constituted by potassium nitrate, water, and isopropyl alcohol were studied by the visual-polythermic method in the temperature range 25–90°C. 1. Most OTC rubbing alcohol has 70 percent isopropyl, the res… In this technique the solution of polymer and protein in partially water-miscible solvent such as acetone is emulsified into aqueous solution containing stabilizer and salting out agent. on Introduction. Other types of salt can also assist with the formation of self-assembled silk particles. The water content of Vodka is too high for the Fitzroy Weatherglass formula. In this case your are not distilling an azeotropic solution of Isopropyl and water but rather separating a liquid from a dissolved solid. Salting out, though rarely used in proteomic studies, provides refolded/native protein conformation after salt removal and significantly reduces sample volume. The solvent is then removed via reduced pressure, followed by ultracentrifugation and repeated washing to eliminate both salting-out agent and stabilizer to yield NPs [8,63]. Step 3: Put the dirt coins into the solution and leave it soak for two hours to a week. 5 years ago. A comprehensive understanding of the salting-out effect has yet to emerge, but it is generally explained by a combination of electrostatic repulsion and enhancement of the hydrophobic effect. Isopropyl alcohol usually retails for about $1.99 - $4.99 per bottle and is widely available at many department stores and pharmacies across the U.S. They'll sometimes deliver at no extra charge too. The effectiveness of a salt at inducing phase separation is largely determined by the anion and tends to parallel the lyotropic (Hofmeister) series [51, 55, 59]. Although rubbing alcohol is very effective for removing some types of stains, such as paint, ink or tree sap, it can also cause stains of its own. Subsequently, reverse salting-out effect leads to precipitation, which aided in entrapment of drug into the polymer matrix, forming the NPs [32]. 1 talking about this. Special care should be given to salt selection as it can have a great influence on the result, even greater than the choice of the extraction solvent. Interesting process to know, but seems like a lot of work to get questionable purity IPA. 11 years ago The function of salting-out agent is generally increased with the increase of the strength of ion. A novel salting‐out extraction process has been developed to separate isopropanol from aqueous solution. ScienceDirect ® is a registered trademark of Elsevier B.V.

You’ll sometimes find isopropyl alcohol sold as rubbing alcohol, but not all rubbing alcohol is made with isopropyl alcohol, so check the label before you buy. I'm guessing but most people would only use 99% Isopropyl for backpack fuel and purity can be asserted with a post-salting out distillation. From Wikipedia "Isopropyl alcohol forms an azeotrope with water, which gives a boiling point of 80.37 °C (176.67 °F) and a composition of 87.7 wt% (91 vol%) isopropyl alcohol." A. Mohammad, in Encyclopedia of Separation Science, 2000. The time you left to … Label the bottle "Dehydrated Isopropyl Alcohol". While denatured alcohol is classified as a methylated spirit, rubbing alcohol is a surgical spirit. Reply Salting-out assisted liquid-liquid extraction is a type of homogeneous liquid-liquid extraction based on the salting-out effect of a water-miscible organic solvent by the addition of substances capable of inducing phase separation from an aqueous solution [51–54]. on Introduction. Typical organic solvents for salting-out assisted liquid-liquid extraction are acetonitrile, acetone, ethanol, isopropanol, dioxane, and tetrahydrofuran [51, 55–58]. When developing a SALLE methodology, the main parameters to be optimized are selection of an organic extracting solvent, selection of a salting-out agent (salt), and optimization of both quantities. They make screw-on filters like car oil filters using that very thing -- silica -- for gasoline dispensers! This step induced hardened polymers. You'd need 2.5x the weight of water in silica gel - that's a fair amount, and salt is easier to come by. … The salting out properties are described by the Hofmeister series. Silica will retain up to 40% of its weight in water. Salting out is a process that can be used to dehydrate Isopropyl alcohol, i.e., separate it from water in an azeotropic solution. Isopropyl alcohol is extremely flammable. 5.9. The main distinction from the conventional emulsion diffusion method is the presence of solvent diffusion step due to the presence of salting agent. Reply Most likely reason why people say to not use iodized salt is because it has iodine which can either A) make I2 which is non polar and may mix with alcohol as apposed to the water or B) could make a iodo-*suffix* compound. These polymers in solution attract water molecules away from the solvation layer around the protein increasing the protein–protein interactions and enhancing precipitation. The function of salting-out agent relates to the ionic potential (z2/R) of salting-out agent, where z is ion valence and R is radius of ion. The Alcohol Cleansing Pads & SmartTab EzRefills are available in unit and dispenser boxes - Wholesale to Public Online @ First-Aid-Product.com - Isopropyl Alcohol Wholesale, Discount, Online! Isopropyl alcohol, acetonitrile, and acetone are the most frequently used solvents in SALLE, whereas magnesium sulfate, ammonium sulfate, sodium chloride, calcium chloride, potassium carbonate, and calcium sulfate are the salts most commonly used as salting-out agents [79]. Table 2.66. Effect of Salting-Out Agent LiNO3 on P350 Extraction of Pr3 + and La3 + (Extractant 70% P350-Kerosene; Concentration of Rare Earths: 0.6 mol/L of La(NO3)3, 0.6 mol/L of Pr(NO3)3, and 0.5 mol/L of HNO3; and O/A = 2.5:1) [13]. The salts initially impede the miscibility of organic phase into aqueous solution, forming emulsion. 3. Phase separation can be induced by a change in temperature, ion-pair formation, the addition of a third solvent, the addition of sucrose, or the addition of an inorganic salt. Can this work with Vodka? Rubbing alcohol is the term used to describe either ethanol-based liquids or isopropyl alcohol. In selecting a particular salt for an application, the cardinal guiding principles are as follows: (1) the salt should have low solubility in the water-miscible organic solvent; (2) the salt should have high water solubility; and (3) the ability of the salt to precipitate hydrophobic substances should be high (based on the lyotropic series). Isopropyl alcohol can be purchased from a pharmacy. Procedure: 1. Silk microspheres formed by the addition of sodium chloride crystals to 6% silk solution. Its freezing point is much lower than that of water. Step 2: Place in zipper storage bags with alcohol Pour a handful of coarse salt and rubbing alcohol (preferably 99% isopropyl, or rubbing, alcohol) into each of the two storage bags until the bowl and downstem are fully submerged. That why I need to get the water out before mixing it. The order of the function of salting-out agent [13] is. Dorota Wianowska, ... Malgorzata Olszowy, in Handbook on Miniaturization in Analytical Chemistry, 2020. An additional aspect to be considered is that the solubility of the salt in the organic solvent must be negligible but very high in water to maximize the interactions between the salt and the water molecules. Usually ammonium sulfate is used as the salt. decant the isopropyl alcohol from the brine. Salting-out assisted liquid-liquid extraction is well suited to the analysis of polar compounds not efficiently extracted by conventional water-immiscible organic solvents but is not limited to polar compounds only. i have to buy new spray bottles all the time The spray bottle full of alcohol is one of the most useful things in my shop. More information about drying agents. 11 years ago The salt dissolves in the water, but is insoluble in isopropyl alcohol, making the water heavier and separate to the bottom while the isopropyl alcohol floats on the top. To separate the salt residue from the Isopropyl use a homemade still. The opposite phenomenon, salting in, is also observed in liquid-liquid extraction, but need not concern us here. quite a bit late but iodized salt really doesn't have that much iodine. 2. 12 years ago If you are, then you must be no stranger to using rubbing alcohol. • 95% ethanol or 91 or 100% isopropyl alcohol can be used to precipitate the DNA. There are two reasons why rubbing alcohol may cause stains. Maybe you should post that as your own instructable...How to Get 99.99%-Pure Isopropyl Alcohol.Step 1: Buy it.You could start your own Instructable channel! The extraction rate and distribution ratio increase with increasing the concentration of salting-out agent. 7.3. Salting out is a special case of partition chromatography: addition of salt to a bulk solution decreases the solubility of organic nonelectrolytes (and weak electrolytes) to the bulk solution. That is a savings of over 63%. This effect is very interesting for sample preparation since simultaneous extraction of various compounds, including hydrophilic ones, into the organic solvent with their simultaneous concentration can take place, allowing analysis to be performed directly in the organic phase or after a simple dilution [79]. (a) Conversion of soluble silk to solid particles (salting out efficiency) as a function of ionic strength of potassium phosphate; inset shows microscopic image of the particles formed at the desired pH. Effect of the Concentration of the Salting-Out Agent LiNO3 on the Separation Factor With P350 in Extraction of Rare-Earth Elements [13] (70% P350-Kerosene, 0.92 mol/L of RE(NO3)3, and 0.5 mol/L of HNO3). Think of the possibilities. This precipitation procedure purifies the proteins in their native form while maintaining the activity of a protein, particularly in the case of enzymes. When a piece is soaked in hot water beforehand, iso is even more effective. In overall situation, the salting-out agent can increase the separation factor of adjacent rare-earth elements as shown in Tables 2.63 and 2.64. The hydrophobic patches on the protein surface generate highly ordered water shells. In this case, the mixing solution of isopropyl alcohol and water forms a positive azeotrope. You may find that your salted out Isopropyl leaves a salt residue when it is burned. on Introduction. Isopropyl alcohol | CH3CHOHCH3 or (CH3)2CHOH or C3H8O | CID 3776 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. The process is colloquially called salting out, and causes concentrated isopropyl alcohol to separate into a distinct layer. This process is called “salting out,” or “salt-induced phase … Salt alters the free energy of unfolded soluble proteins leading to aggregation, nucleation and growth into spheres (Slotta et al., 2008). In this method the water-miscible solvent in which the polymer and protein are dissolved separates from the aqueous solution on addition of salts such as magnesium chloride, calcium chloride, etc. Phase separation can be induced by a change in temperature, ion-pair formation, the addition of a third solvent, the addition of sucrose, or the addition of an inorganic salt. Accordingly, salting out efficiency of potassium phosphate is better than sodium chloride because HPO2−4 is ranked above Cl− and similarly K+ is above Na+ in the Hofmeister series. Surbhi Dubey, ... Suresh P. Vyas, in Nanobiomaterials in Drug Delivery, 2016. Effective salts are K 2 CO 3, ... As a result, isopropyl alcohol-water mixture the concentration of which is less than 87.4wt% has been concentrated to 95.6wt% isopropyl alcohol. In the first step, the nucleic acids are precipitated with low concentration of ammonium sulfate (around 30%, w/v), the precipitate is spun down and proteins are salted out using 65% w/v ammonium sulfate. The main concept of SALLE is presented in Fig. If you use it to dry your gasoline then be sure to remove the residual salt using the addendum method. The main advantage of a salting out procedure is that it minimizes the unfolding stress to protein encapsulates. Salting out was tried to separate isopropyl alcohol-water azeotropic mixture and the 25 salts were examined to observe the salt effect on this system. 10 years ago "Salting Out" Alcohol From Water Add salt to isopropyl alcohol to process by azeotropic distillation. Just find your local chemical company. Our Isopropyl Alcohol is available in 70% and 99%, in quart bottles, pump spray, and even gallons! The salting out method minimizes the problem of unfolding or inactivation of protein during encapsulation. The ideal salt for protein precipitation is most effective for a particular amino acid composition, is inexpensive, and is nonbuffering. P. Novák, V. Havlíček, in Proteomic Profiling and Analytical Chemistry (Second Edition), 2016. Open jar carefully so as not to remix the two layers. Various peptides are nanoencapsulated on a different nanoparticulate system using this technique. The higher the concentration of salting agent, the higher the separation factor of adjacent rare-earth element. Are you prone to getting minor cuts and wounds? think money*(*99.9% Isopropyl Iso-Heet at auto stores runs around 18.25 cents per ounce. Ion strength is μ=∑i12cizi2, where c is the mole concentration of ions and z is the valence of ions. As the salt concentration of a solution increases, more of the bulk water becomes associated with the salt ions. Proteins assume structures in aqueous solutions that minimize the contact of the hydrophobic amino acid residues with the solvent (water), and maximize the contact between the polar amino acid residues and the solvent. Sidewinder Solvent Recycler, Las Vegas, Nevada. It offers an alternative for the extraction of compounds with low mass and high polarity that are not efficiently extracted by liquid-liquid extraction. Removing water also increases the Isopropyl alcohol's ability to: Polymers, such as dextrans and polyethylene glycols, can also precipitate proteins, and they are less likely to denature the biomaterials than isoelectric precipitation. ‰Use at least 90% concentration of isopropyl alcohol; 99% is best. 2 years ago. . 99.9% Isopropyl made from salting out 50%-91% generic retail brand Isopropyl runs around 6.73 cents per ounce. It’s relatively inexpensive and widely available at your local drugstore, usually located in the first aid aisle. Reply Effect of Salting-Out Agent on the Extraction of Pr and Nd With TBP [2] (100% TBP, 120–150 g/L of REO, and Salting-Out Agent is Close to Saturation), Table 2.64. Salting out is a modified formulation of emulsion process in fabricating polymer encapsulated lipophilic drug via salting-out agent. Does silica gel absorb isopropyl alcohol? Reply Railroad Rail Lantern / Sign Stand Split With Axe. on Introduction, sounds like a illegal substance lol starts with a m. If you're hinting at "methanol", it's not illegal. This should help remove left over salt water and other potentially unwanted minerals … For example, silk microparticles formed along with silk gel when sodium chloride crystals were added to a 6% aqueous silk solution during preparation of salt leached porous scaffolds (Fig. Instead, you can scrub them out with pipe cleaners or cotton swabs. R. Rajkhowa, X. Wang, in Silk Biomaterials for Tissue Engineering and Regenerative Medicine, 2014. However, the growing interest in SALLE results from the possibility of extracting compounds with a wide polarity range from polar biological matrices [77, 78, 84]. In this process, salting-out agents play prominent role in manufacturing polymer encapsulated drugs NPs. Rubbing alcohol is just one of the many home remedies discussed on the internet for acne. Tables 2.65 and 2.66 list the effect of salting-out agent on separation factors. Salting-out assisted liquid-liquid extraction is the enabling technique incorporated in the QuEChERS method for the multiresidue analysis of pest control compounds in foods and environmental samples [60]. The solution is then diluted with water to allow the diffusion of organic solvent into water and formation of polymer- and drug-containing organic droplets forming nanospheres followed by subsequent removal of salting out agent and solvent by cross-flow filtration (Figure 4.3). Copyright © 2021 Elsevier B.V. or its licensors or contributors. In general terms, Miniaturized methods of sample preparation, Dorota Wianowska, ... Malgorzata Olszowy, in, Handbook on Miniaturization in Analytical Chemistry, Proteomic Profiling and Analytical Chemistry (Second Edition), ION ANALYSIS | Thin-Layer (Planar) Chromatography, Silk Biomaterials for Tissue Engineering and Regenerative Medicine. Methanol is poisonous! Which is a mixture of camphor, ammonium chloride, potassium nitrate, water and ethanol. Salting out is a process that can be used to dehydrate Isopropyl alcohol, i.e., separate it from water in an azeotropic solution. CAUTION: Isopropyl alcohol is flammable and poisonous. In many applications like a pocket stove the salt residue will continue to serve in the role of helping to separate the Isopropyl and the water when water intrusion occurs from dampness, rain or boil overs. Schematic representation of salting out method for preparation of polymeric nanoparticles. 5.9. For practical applications, only salt addition and to a lesser extent sucrose addition are important. Polyacrylonitrile is the most suitable sorbent for the separation of complexes. It wil react with the water to form Ca (OH)2. Removing water also increases the Isopropyl alcohol's ability to:> melt ice off your frozen windshield> dissolve water in gasoline> burn cleaner when used as a standalone fuel> provide your pet with an invigorating rub after his next bath, which is curiously strong enough (dry enough) to dislodge stubborn ticks and fleas> serve as a powerful pet or human wound antiseptic> wash out those wax filled ears> save you big $$$ (dough, ka-ching, moola, etc.) All silk material formed particles if the ionic strength was 0.75M or higher (Lammel et al., 2010). Put the lid on the jar, close to seal the contents and shake jar vigorously to be sure the salt and water combine. Small, multiply charged anions with a high charge density such as sulfate, phosphate, and carbonate salts of magnesium, calcium, and potassium are typically used while many early reports employed sodium chloride, although this is not expected to be as efficient as the salts just mentioned. Protein during encapsulation solution is slowly added to a lesser extent sucrose addition are important are chloride.
