Abstract

PURPOSE:To lengthen the life of membrane by a simple means in which cation exchange membrane polluted in alkali chloride electrolysis is regenerated by electrifying both cathodic and anodic electrolytes acidified in electrolytic bath. CONSTITUTION:During electrolysis of alkali chloride aqueous solution with cation exchange membrane, the cation exchange membrane is polluted with impurities present in the alkali chloride aqueous solution. When the polluted cation exchange membrane is fitted in an electrolytic bath with the cathodic and anodic electrolytes both of which are acidified with an acid such as hydrochloric acid, etc., and then electrification is made, the impurities in and on the surface of cation exchange membrane are made soluble and further removed to the outside of the membrane by diffusion. Thus, the regeneration of membrane can be attained by a comparatively simple means and thereby an economical profit due to the lengthening of the membrane life can be obtained.
