Ion exchange technology has a long history, and certain natural materials such as zeolites and sulfonated coals obtained by sulfonation with coal can be used as ion exchangers. The properties and parameters of various resins can be found in the ion exchange resin manual and products. Organic rice protein powder is a vegan and vegetarian protein option that may aid with building and repairing muscle after strenuous exercise. Rice Protein Powder is bioavailable, easily digestible, and heat stable, meaning it can be used in cooking and baking. As an eco-friendly and sustainable alternative to whey, it is allergen-free and does not contain any dairy, soy, or wheat.

Other supplements:
(1) Strongly acidic cationic resin Such a resin contains a large amount of a strong acidic group such as a sulfonic acid group -SO3H, and is easily dissociated from H+ in a solution, so that it is strongly acidic. After the resin is dissociated, the negatively charged groups contained in the bulk, such as SO3-, can adsorb other cations in the bound solution. These two reactions exchange H+ in the resin with the cations in the solution. Strongly acidic resins have strong dissociation ability and can dissociate and produce ion exchange in acidic or alkaline solutions.
After the resin has been used for a period of time, it is subjected to a regeneration treatment in which the ion exchange reaction is carried out in the opposite direction with a chemical to return the functional group of the resin to its original state for reuse. The cationic resin as described above is subjected to regeneration treatment with a strong acid, at which time the resin releases the adsorbed cation and combines with H+ to restore the original composition.
(2) Weakly acidic cationic resin Such a resin contains a weakly acidic group such as a carboxyl group-COOH, which is capable of dissociating H+ in water and being acidic. The remaining negatively charged groups after the dissociation of the resin, such as R-COO- (R is a hydrocarbon group), can adsorb to other cations in the solution to cause cation exchange. The acidity of this resin is weak, it is difficult to dissociate and ion exchange at low pH, and it can only work in alkaline, neutral or slightly acidic solutions (such as pH 5-14). Such resins are also regenerated with acid (more readily regenerated than strongly acidic resins).
(3) Strongly basic anion resin. Such a resin contains a strong basic group such as a quaternary amine group (also known as a quaternary amine group)-NR3OH (R is a hydrocarbon group), which can dissociate OH- in water. Strongly alkaline. The positively charged group of this resin binds to the anion in the solution to cause anion exchange.
This resin is highly dissociable and works well at different pHs. It is regenerated with a strong base such as NaOH.
(4) Weakly basic anion resins These resins contain weakly basic groups such as primary amino groups (also known as primary amine groups) - NH2, secondary amino groups (secondary amine groups) - NHR, or tertiary amine groups ( Tertiary amine groups -NR2, which are weakly alkaline in the water to dissociate OH-. The positively charged group of this resin binds to the anion in the solution to cause anion exchange. This resin in most cases adsorbs all other acid molecules in the solution. It can only work under neutral or acidic conditions (eg pH 1 to 9). It can be regenerated with Na2CO3, NH4OH.
In addition to the above two series of styrene and acrylic, the ion exchange resin can also be made by polymerizing other organic monomers. Examples include phenolic (FP), epoxy (EPA), vinylpyridine (VP), and urea formaldehyde (UA).
Introduction to the variety of ion exchange resins:
Ion exchange resins are available in many manufacturers and many varieties at home and abroad. There are dozens of domestic manufacturing plants, mainly Shanghai Resin Factory, Tianjin Bohong Resin Technology Co., Ltd., Chenguang Chemical Research Institute Resin Factory, Tianjin Nanda Resin Technology Co., Ltd., etc.; more famous foreign companies such as Rohm & Hass Amberlite series, Dow Chemical's Dowex series, French Duolite series and Asmit series, Japan's Diaion series, as well as Ionac series, Allassion series and so on. Most of the resin grades are specified by each manufacturer or country. Some foreign products use the letter C for cationic resin (C is the first letter of cation), A for anionic resin (A is the first letter of Anion), such as Amberlite's IRC and IRA are cation resin and anion resin, respectively. Represents cation resin and anion resin, respectively. China's Ministry of Chemical Industry regulations (HG2-884-76), the type of ion exchange resin consists of three Arabic numerals. The first digit represents the classification of the product: 0 for strong acidity, 1 for weak acidity, 2 for strong alkalinity, 3 for weakly basic, 4 for chelation, 5 for amphoteric, and 6 for redox. The second digit represents a different skeleton structure: 0 represents a styrene system, 1 represents an acrylic system, 2 represents a phenolic system, and 3 represents an epoxy system. The third digit is the sequence number, which is used to distinguish the difference between the matrix, the crosslinking group, and the like. In addition, the macroporous resin is preceded by a letter D. Therefore, D001 is a macroporous strong acid styrene resin. Brand Resin structure product name Functional basis Full exchange
