Temperature dependence of the cathodic and anodic kinetics in a copper electrowinning cell based on reactive electrodialysis
The temperature dependence of various kinetic parameters for the copper electrodeposition reaction and for the ferrous to ferric ion oxidation has been experimentally determined. Potentiodynamic sweeps were carried out in a reactive electrodialysis cell in the 30– 60 ∘ C range in order to obtain exp...
