【Abstract】 In this paper, the theory of first derivative cyclicvoltammetry at stationary ultrami-crocylinder electrodes is presented. The characters of the voltammogram curves are discussed. An experimental study was made with a JP3-1 type of oscillopolarograph at platinum wire ultra-microcylinder electrodes in K4Fe(CN)6 solution. The experimental results are in good agreement with the theory.更多还原
