Electrodialysis method using ion exchange membranes
Abstract
Abstract NEGATIVELY CHARGED FIXED GROUPS AND (2) FINELY PULVERIZED WATER-SOLUBLE SOLID ELECTROLYTES GAVING NEGATIVELY CHARGED FIXED GROUPS IN THE WATER DECOMPOSITION COMPARTMENTS AND PASSING A DIRECT CURRENT BETWEEN THE ELECTRODES. POLYVALENT METAL IONS IN A VALENCE STATE OF AT LEAST 2 MAY BE ADDED TO SAID SOLUTION OR SUSPENSION. HYDROGEN IONS AND HYDROXYL IONS ARE GENERATED ECONOMICALLY IN AN ELECTRODIALYSIS CELL COMPRISIED OF A PLURALITY OF ANION EXCHANGE MEMBRANES AND CATION EXCHANGE MEMBRANES ALTERNATELY JUXTAPOSED BETWEEN A PAIR OF AN ANODE AND A CATHODE BY FILLING AQUEOUS SOLUTION OR SUSPENSION CONTAINING AT LEAST ONE ELECTROLYTE WHICH IS INCAPABLE OF PASSING THROUGH THE ION EXCHANGE MEMBRANE AND IS SELECTED FROM THE GROUP CONSISTING OF (1) WATER SOLUBLE POLYELECTROLYTES (POLYMERIC ELECTROLYTES) HAVING
