Abstract:

The purpose of this paper is to propose mathematical modeling of different kinds of electrochemical processes. Electrooxidation of nitrite ions on some types of electrodes (glassy carbon, screen-printed carbon-containing, gold, and gold nanoparticles) and oxidation of ascorbic acid on gold electrodes nonmodified and modified by gold nanoparticles were used for the comparison of calculated and experimental data. It is shown that in each case, a specific shape of the voltammogram helps to identify the mechanism of the process. The comparison of the theoretical and experimental data shows that the process of oxidation of nitrite ions causes passivation of the electrode by adsorbed products of electrooxidation, and nanoeffects are not observed at that. Nanoeffects were observed in the oxidation of ascorbic acid on gold nanoparticles localized on gold electrode.
