Abstract

PURPOSE:To prevent the production of chlorine dioxide as a by-product and to efficiently remove chlorate when hydrochloric acid is added to salt water for electrolyzing an aq. alkali chloride soln. and chlorate in the salt water is decomposed and removed, by keeping the concns. of the hydrochloric acid and chlorate in the salt water at prescribed values. CONSTITUTION:Salt water for electrolyzing an aq. alkali chloride soln. by a cation exchange membrane method is introduced into a chlorate decomposing tank. Hydrochloric acid is added to the tank and the concn. of the hydrochloric acid in the salt water is kept at 10-50g/l. The concn. of chlorate in the salt water is kept at <=1g/l (expressed in terms of ClO3<->). The chlorate in the salt water is then removed. The production of chlorine dioxide as a by-product is prevented and the chlorate in the salt water is efficiently decomposed and removed.
