Abstract
A cylindrical cation exchange membrane is described for use in electrolysis of an aqueous alkali metal chloride solution in a finger type electrolytic cell, wherein the equivalent weight of the area not facing the effective electrolytic surface of anode is greater than the equivalent weight of the areas facing the effective electrolytic surface, thus permitting a reduction of the alkali metal chloride content of an effluent from a cathodic chamber.
