Anotace

V originále

The electrode reaction mechanism of electrolytical coating by nickel, cobalt and nickel+cobalt on paraffin impregnated graphite electrode was investigated by cyclic voltammetry and elimination voltammetry with linear scan (EVLS). During the electrodeposition of metals on the graphite electrode, hydrogen evolved from aqueous acid solutions decreases cathodic efficiency of the plating process. The elimination of major kinetic current arising due to hydrogen evolution enables one to study the minor processes proceeding at the electrode. Cyclic voltammograms were measured at three scan rates: 12,5 mV/s, 25 mV/s and 50 mV/s and the EVLS functions were calculated for one or two eliminated currents. The results indicate the occurrence of surface reactions with the adsorption of intermediates on graphite. The application of EVLS provides deeper insight into the mechanism of electrode reaction during metal deposition.
