Reactant adsorption in cyclic staircase voltammetry on spherical microelectrodes. Reversible redox reactions

On spherical microelectrodes, cyclic staircase voltammograms of reversible redox reactions complicated by the reactant adsorption on lateral interactions in the monolayer. Attraction forces increase the separation between the main wave and post-peak, while the repulsion prevents the resolution of responses of the surface and volume reactions. The theoreticla relationships between the dimensionless responses and the dimensionless adsorption constant, the relative surface adsorption capacitvy, the Frumkin coefficient and the electrode spheriicity are given.
