TREATMENT OF LIQUIDS WITH ETHYLENE COPOLYMER TO REMOVE METAL IONS; COPOLYMERS OF ETHYLENE WITH 1-CHLORO-2-HYDROXYPROPYL-TRIMETHYL AMMONIUM ACRYLATE

摘要

A method of removing dissolved metal contaminants from aqueous and/or organic liquids by contacting the liquids with ethylene polymer having pendent carboxylic acid groups or pendent carboxylic acid groups in the salt form which polymer is in microporous, fibrous or particulate form for a time sufficient to cause metal ions to affix to the polymer and thereafter separate the liquid from the polymer.
