Abstract: As polarographic behavior of catalytic wave by controlled current method has been rarely investigated, a current scanning polarograph was constructed and catalytic wave of vanadium (III)-EDTA was measured for comparing it with the result which was already obtained by using conventional polarograph. Although diffusion and catalytic currents (id and ic) were influenced by the reversibility of the supporting electrolyte as shown in theory, the rate constant, kobs, of the redox reaction between vanadium(II)-EDTA and nitrate ion was in agreement with that obtained by ordinary polarography. So, it may be allowed to use a current scanning polarograph for the measurements of catalytic phenomena in polarography.
