Claim Text:
1. A metal- and ion-adsorbing polymer adsorbent, produced by: dissolving a reactive polymer having halogenated alkyl groups or glycidyl groups and a base material polymer insoluble in water and alcohols and having no halogenated alkyl group or glycidyl group in an organic solvent capable of dissolving both of the reactive polymer and the base material polymer, thereby forming a uniform mixed solution; removing the organic solvent from the mixed solution, thereby forming a solidified carrier in a desired form; and allowing the halogenated alkyl groups or the glycidyl groups in the solidified carrier to react with a metal- and ion-adsorbing amine compound having amino groups or imino groups, thereby introducing an adsorptive functional group, wherein the metal- and ion-adsorbing amine compound is selected from ethylenediamine, polyethyleneimine, polyallylamine, a partially carboxymethylated compound thereof or a polycarboxylic acid or polyamide having an amino group or an imino group, and wherein the reactive polymer is crosslinked with the metal- and ion-adsorbing amine compound in the solidified carrier by the reaction between the halogenated alkyl groups or the glycidyl groups of the reactive polymer and the amino groups or the imino groups of the metal- and ion-adsorbing amine compound.
