The process of electroreduction of copper from the water-ethanol solutions of copper sulphate on the copper electrode was studied with the use of polarization and impedance techniques. It is shown that at potentials of the working electrode in the range -0.6 ÷ -0.8 V the rate-limiting step of the process is the diffusion of copper ions to the electrode surface. The diffusion coefficient of copper ions at ethanol concentration of about 0.08 ppm takes the minimum value due to restructuring of the pre-electrode layer at a given concentration of alcohol. |
