ion exchange resin with basic functional groups that can exchange with anions in solution. The alkalinity of functional groups varies and can be roughly divided into two categories: strong alkalinity and weak alkalinity. The strongly basic anion exchange resin with quaternary ammonium group, the strongly basic type containing trimethylamino group in the quaternary ammonium type, the strongly basic type containing dimethylethanol amino group, and the weakly basic ion exchange resin containing primary amine, secondary amine, and tertiary amino group.
