| Abstract Scope |
In the aqueous electrowinning of metals such as copper, nickel, cobalt, etc., the respective ions are reduced at cathode in an electrochemical cell while the anodic reaction is water oxidation. Similarly, during electrodeposition of metal oxides such as Electrolytic Manganese Dioxide (EMD) that takes place at anode, water redox reaction takes place at cathode. In the present work, simultaneous electrodeposition
of nickel at anode and EMD at the cathode using membrane cell was investigated. The process can lead to reduction in the energy consumption during simultaneous electrodeposition compared to the energy consumed during deposition of nickel and EMD in two independent cells. This also reduces number of cells and therefore reduces capital cost. The parameters such as type of membrane, bath temperature, current density have been varied and its effect on the cathodic and anodic current efficiency has been studied. The quality of deposits and the design issues are discussed. |
