Process for producing a bifunctional filter membrane having iminodiacetic acid groups

摘要

A process for producing a filter membrane capable of simultaneous removal of metallic ions and nonionic materials from process water used in electronics industry, medical field, pharmaceutical industry and nuclear power generation. The membrane is produced by introducing iminodiacetic acid groups to a porous membrane made from polyolefin or a copolymer of an olefin and a halogenated olefin by uv or ionizing radiation initiated graft polymerization.
