The invention discloses a preparation method of a cuprous ion immobilized carrier, which is characterized by comprising the following steps: the cuprous ion immobilized carrier of the present invention is a porous polymer microsphere, and based on the swellable seed polymer microsphere, The polymerized specific monomers, porogens, cross-linking agents, and initiators are swelled in the seed microspheres. After the polymerization reaction, the post-modification reaction is carried out to obtain polyhydroxy cation-exchange microspheres; the ascorbic acid and copper ions are adsorbed again, and the on-line reduction is obtained. Cuprous ion immobilization carrier. |
