Abstract
Cyclic voltammetry and chronoamperometry were used in order to study the reaction mechanism and the transport parameters of the electroactive species at the W and GC electrodes. The results showed that the electrochemical reaction is irreversible and that electrocrystalization of Co plays an important role in the electrodeposition process. Experimental current-time transients have been compared with the theoretical models based on instantaneous and progressive nucleation.
Mass transport towards the electrode is a diffusion process, and the diffusion coefficient of Co(II) and the activation energies for diffusion have been calculated.
