The equation of normal pulse voltammetry for reversible wave at micro-ring electrode is presented and its current-potential characteristics are discussed. Tests are carried out to verify the equation and the theor. conclusions are in good agreement with experimental data for K4Fe(CN)6 in the presence of 0.5 mol/dm3 KCl at gold and platinum electrode.
