Preparation and Properties of Al/Pb-Ag-Co Composite Anode Material for Zinc Electrowinning

摘要：

　　The Al/Pb-0.3wt% Ag-0.01wt% Co composite anode material was prepared by dec trodeposition.The electrochemical properties of the composite anode in 50 g/L Zn2+ and 150 g/L H2SO4 solutions were investigated by anode polarization curves, cyclic voltammetry(CV) curves and Tafei curves.The surface structure were analysised by SEM and EDS.The results showed that the cobalt inclusions can reduce the oxygen evolution potential and improve the corrosion resistance.Compared with cast Pb-0.3wt% Ag, the electrode surface morphology of the Al/Pb-0.3wt% Ag and Al/Pb0.3wt% Ag-0.01wt% Co was more dense, the grain was smaller.
