A unified treatment of reversible electrode processes in voltammetric techniques and chronopotentiometric techniques with programmed current

摘要

In this paper we demonstrate the existence of a total analogy between the potentiostatic and chronopotentiometric responses when a constant potential E and a programmed current of the form I(t) = I_0t~u, u >= -1/2, respectively, are applied to planar and spherical electrodes, and also to hemispherical microelectrodes. From the above analogy, we also compare differential pulse voltammetry (DPV) and a new reciprocal derivative chronopotentiometric technique proposed in this paper.
