FIELD: recovery of liquid wastes including extraction of noble metals from them.
SUBSTANCE: proposed method for electrochemical extraction of palladium from nitric acid solutions includes settling, washing, and dissolution of metal palladium obtained. In the process solution incorporating palladium and 0.5 0- 4.5 mole/l of nitric acid is brought in contact with shorted-out bimetal pair one of whose components is aluminum.
EFFECT: enhanced degree of cleaning palladium from foreign impurities.
