POLYVALENT CATIONIC ION ADSORBENT MATERIAL CAPABLE OF THERMAL DESORBING, ITS PRODUCTION METHOD AND RECOVERY METHOD OF POLYVALENT CATIONIC ION

摘要

PROBLEM TO BE SOLVED: To provide a polyvalent cationic ion adsorbent material capable of thermally desorbing with a high speed of adsorbing and desorbing having enough adsorbing performance of the cationic ion and having enough desorbing performance of the cationic ion. SOLUTION: A polyvalent cationic ion adsorbent material capable of thermal desorbing is comprised of anα,β-ethylenic unsaturated monomer having a dibasic acid group, anα,β-ethylenic unsaturated monomer having a reactive group capable of forming a bridge and/or a monomer having more than twoα,β-ethylenic unsaturated groups and as needed, is comprised of a copolymer bridged by theα,β-ethylenic unsaturated monomer capable of copolymerizing with these monomers and/or a copolymer bridged by an after-treatment reaction.
