FIELD: chemistry.
SUBSTANCE: method includes the processing of copper sediments with a solution, which contains ammonia, hydrogen peroxide, glycerine and water in the ratio of (3-4):(0.5-1):(1-2):(1-1.5) respectively, with processing being carried out for 20-30 minutes at room temperature.
EFFECT: invention makes it possible to increase the efficiency of purification, and reduce the temperature and duration of the metal surface purification from copper sediments.
