Abstract

PURPOSE:To decrease chloride ion concentration in the caustic alkali solution obtained in cathode bath. It is achieved in the electrolysis process of alkali choride solution using water permeable diaphragm by causing undecomposed alkali choride solution to contact with reducing agent and making it circulate into anode bath.
