Investigations on cyclic reciprocal derivative chronopotentiometry .1. Theory for a reversible reaction

A new electroanalytical method for studying the electrode reactions, called cyclic reciprocal derivative chronopotentiometry, is proposed. The applied current is successively reversed at each transition, and the reciprocal of the time derivative of the electrode potential, dt/dE, is recorded vs. E. A circuit for providing the reciprocal signal and the carrying out the automatic current reversals is developed. The equations describing the first cycle of the dt/dE-E chronopotentiogram for a reversible reaction have been deduced and experimentally verified.
