FIELD : chemistry.
SUBSTANCE : method of extracting lead (II) ions (Pb2+) from acidic solutions involves sorption of Pb2+ ions by bringing the solution into contact with an anionite. Sorption is carried out at 70-80° C from solutions containing 80-120 g/l hydrochloric acid and chlorides of ammonia, alkali or alkali-earth metals on an AMP anionite which contains exchange groups or on an AM-2b anionite which contains exchange groups pre-treated with distilled water.
EFFECT : finding optimum conditions for efficient sorption of lead ions.
