FIELD: hydrometallurgy; manufacture of ionite membranes.
SUBSTANCE: proposed method includes hot molding at simultaneous reinforcing of mono-polar sulfo-cationite membrane and membrane on base of benzyl trimethyl ammonium anionite. Layer molded between mono-polar membranes over working section contains phosphorus-organic compound including estereal oxygen in alkyl radicals and nitrogen-phosphorus containing polyampholyte.
EFFECT: improved electrochemical properties of membrane; low cost of initial materials; extended range of application.
