Abstract

A reaction mechanism is proposed for the explanation of the anodic passivation far Cd in NaHC03 solution, supposing it is due
to the adsorption of electrochemical oxidation products on the metal surface. The mechanism is studied mathematically and theoretically. Potentiodynamic and chronoamperometric curves are deduced. Theo­retical potentiodynamic curves are fitted to experimental data by means of a non-linear least squares method. Kinetic parameters are calculated together with the ratio true electrode area to geometric area. The dedu­ced kinetic parameters are substituted into the theoretical chronoampe­rometric equation and compared with the experimental curve.
