- 摘要：
PROBLEM TO BE SOLVED: To provide cationic exchange resin that maintains a high exchange speed of polyvalent ions in addition to monovalent ions without agglomeration occurring in spite of surface coating even when mixed bed ion-exchange resin is used.
SOLUTION: The cationic exchange resin is modified with a water-soluble cationic polymer electrolyte, which has an intramolecular cyclic quaternary ammonium salt structure in the molecule. Further, a mixed bed ion-exchange resin contains cationic exchange resin and anionic exchange resin.
