Study on Electrodeposition Recovery of Cupric and Zinc in Complexation Ultrafiltration Process

Electrodeposition recovery of heavy metals in concentrated solution of wastewater treatment by complexation ultrafiltration was studied. In the study, cheap plategraphite electrode was applied in the traditional electric cell reactor. Current density and mass concentration of the electrodeposition for cupric and zinc recovery were discussed, and the optimal condition were determined. The results showed that the current efficiency of cupric and zinc recovery were more than 60%, and corresponding power consumptions were 11.5 kW·h/kg and 14.0 kW·h/kg, respectively.
