| Abstract: | Electrolysis of silver in 95-84 wt % sulfuric acid with addition of 40 g l-1 of silver sulfate was studied at electrolyte temperature of 40°C. The optimal conditions of silver electrolysis in 84-85 wt % sulfuric acid were determined. Semicommercial tests of the electrochemical recovery of silver from silver coatings on copper, brass, aluminum, and steel articles were performed. |
