ION-EXCHANGE FIBERS AND METHOD FOR PRODUCING SAME, METHOD FOR REMOVING AND ADSORBING CHEMICAL SUBSTANCE IN WATER, AND DEVICE FOR REMOVING AND ADSORBING CHEMICAL SUBSTANCE IN WATER

摘要

Provided is an ion-exchange fiber including a polymer A obtained by introducing an ion-exchangeable substituent to 100 parts by weight of an acrylic polymer that is obtained by polymerization of a monomer composition containing 30% by weight or more of acrylonitrile with respect to 100% by weight of the composition and a polymer B obtained by introducing an ion-exchangeable substituent to 1 part by weight or more and 100 parts by weight or less of an epoxy group-containing polymer. Each ion-exchangeable substituent is introduced by reaction with an amine compound and is an ion-exchangeable substituent derived from the amine compound. A method for producing the ion-exchange fiber is also provided.
