Electrolytic oxidation of ferrocene in acetonitrile with or without supporting electrolyte in a quiet solution yielded nearly steady-state currentpotential response at a platinum semimicro-disk anode. A short platinum wire, immersed in the same solution served as a quasi reference electrode. The investigation suggests that a two electrode configuration utilizing a powersupply unit furnishes results similar to those obtained with three-electrode configuration and a voltammeter.
