overview
Cation exchange resin is an ion exchange resin containing acidic groups in the molecule. Can swell in water or polar solvent. The aqueous solution is acidic and can be exchanged with the cations in the solution with its hydrogen ions or potassium and sodium ions.
category
According to the ionization constant of acidic active groups, it can be divided into three categories: strong acid, medium acid and weak acid. Strong acid cation exchange resin contains sulfonic acid group-SO3H, medium acid cation exchange resin contains phosphoric acid group-H2PO4 or phosphonic acid group-H2PO3. The weakly acidic cation exchange resin contains carboxyl-COOH or phenolic hydroxyl.
application
Cation exchange resin is an ion exchange resin containing acidic groups in the molecule. H on the active groups can act with the cation exchange of the test solution to achieve purification, separation, purification, and removal of interference.
application progress
cation exchange resin was first used in the extraction and separation of antibiotics, vitamin concentration and purification, etc. In recent years, with the further development of ion exchange technology and interdisciplinary, ion exchange resins have been increasingly used in traditional Chinese medicine preparations, including drug development, composition analysis, preparation technology and other links.
