Abstract: The anodic reaction kinetics of zinc electrowinning was investigated on the titanium base RuO2anode in the system of Zn(Ⅱ)-NH3-NH4Cl-H2O. The effects of stirring speed, ammonium chloride concentration and temperature on anodic reaction rate were studied through the curve measurement of potentiostatic polarization. The results reveal that the electrochemically controlled anodic reaction obeys Tafel equation and the anodic reaction order for ammonium chloride is 1. 056, with the apparent activation energy of 40.17 kJ/mol. The general equation of anodic reaction kinetics was obtained.
