POLYMER ADSORBENT

摘要

Problem To provide a method for easily producing an adsorbing material used for the removal and recovery of metals and ions in a solution, which is highly durable and has various adsorptive functional groups and forms applicable for various purposes.;Means for Resolution A polymer adsorbent for metals and ions, which is highly durable and has various adsorptive functional groups and forms applicable for various purposes, is produced by a) preparing a reactive polymer having a large number of halogenated alkyl groups or glycidyl groups in the molecule, b) preparing a base material polymer insoluble in water and alcohols, c) dissolving the reactive polymer and the base material polymer in an organic solvent to give a mixed solution, d) removing the organic solvent to give a solid carrier in a desired form, and e) allowing a halogenated alkyl group or a glycidyl group in the solid carrier to react with an amine compound having a functional group capable of adsorbing metals and ions, thereby introducing an adsorptive functional group.

主权项

1. A metal- and ion-adsorbing polymer adsorbent, characterized by being produced by:
dissolving a reactive polymer having a large number of 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 each, 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 a halogenated alkyl group or a glycidyl group in the solidified carrier to react with a metal- and ion-adsorbing amine compound, thereby introducing an adsorptive functional group.
