Abstract

A salt of a strongly-basic quaternary ammonium anion exchange resin (comprising the reaction product of an insoluble cross-linked vinyl aromatic resin containing haloalkyl radicals on the aromatic nuclei and a tertiary amine) having monovalent anions attached to the nitrogen atoms of the quaternary ammonium groups, is regenerated by first contacting the resin salt with an aqueous solution of an alkali metal carbonate, phosphate or sulphate to replace the monovalent anions by polyvalent anions, and thereafter contacting the resulting resin salt with an aqueous solution of an alkali metal hydroxide to replace the polyvalent anions by hydroxyl ions.
