Abstract

An analytical application of chronoamperometry for determination of electroactive species not requiring standardization is described in this paper. It is based upon the separation of current component limited by linear diffusion from that limited by cylindrical contribution to the total flux of determined substance to the cylindrical (wire) Pt-semimicroelectrode (radius 0.02 mm and length 15 mm). The absolute method of determination was verified with <i>o</i>-dianizidine, ferrocyanide, ascorbic acid and dopamine. The optimalization of radius of the cylindrical electrode to minimize the determination error is also presented.
