摘要：

The electrowinning of cadmium in the presence of zinc has been investigated. As such, the effects of initial cadmium concentration (40-160 g/L), current density (50-150 A/m(2)), free acid concentration (0-196 g/L), initial zinc concentration (20-120 g/L), and temperature (25-70 degrees C) on current efficiency (CE) and specific power consumption (SPC) in electrowinning of cadmium have been examined. Under the optimum working conditions (initial cadmium concentration 120 g/L, current density 80 A/m(2), free acid concentration 98 g/L, and temperature 40 degrees C), CE and SPC were 98% and 1.21 kWh/kg, respectively. The presence of zinc (20-120 g/L) had no systematic effect on CE and SPC, but decreased the purity of the deposited cadmium down to 99.92%. (C) 2010 Elsevier B.V. All rights reserved.
