GOST 20298-2022 PDF

Scope: This standard applies to strongly acidic and weakly acidic cation exchangers, which are high-molecular polymer compounds with a three-dimensional gel and macroporous structure containing acidic functional groups capable of cation exchange reactions. Cation exchangers are insoluble in water, solutions of mineral acids, alkalis and organic solvents. Cation exchangers are intended for purification, extraction, concentration and separation of substances in various fields of industry, for analytical purposes, and also as catalysts in organic synthesis
