FIELD: bipolar membrane used in hydrometallurgy and method for manufacturing the same.
SUBSTANCE: method involves providing simultaneous joint hot pressing and reinforcement with synthetic fabric from monopolar filaments of sulfocationite membrane based on macroporous sulfocationite with highly developed surface having specific surface value equal to 10 m2 and membrane based on benzyltrimethyl ammonium anionite. Both membranes are manufactured with the use of low-pressure polyethylene.
EFFECT: improved electromechanical properties of membrane.
