PROBLEM TO BE SOLVED: To provide a method for easily and simply producing a durable adsorbent which is used for removal/recovery of a metal or ionic species in a solution and has various adsorptive functional groups and forms applicable to various applications.SOLUTION: A durable polymer adsorbent for a metal and ionic species which has various adsorptive functional groups and forms applicable to various applications is produced by: (a) preparing a reactive polymer having many halogenated alkyl groups or glycidyl groups in the molecule; (b) preparing a base polymer insoluble in water or an alcohol; (c) obtaining a mixed solution by dissolving the reactive polymer and the base polymer in an organic solvent; (d) obtaining a solid carrier having a desired form by removing the organic solvent; and (e) introducing an adsorptive functional group by reacting the halogenated alkyl groups or glycidyl groups in the solid carrier with an amine-based compound having a functional group capable of adsorbing the metal and ionic species. |
