Investigations on reversible wave theory of theory of differential pulse voltammetry at polyaniline thin film-coated electrodes

Abstract

A theor. equation describing the reversible wave in differential pulse voltammetry at polyaniline thin film-coated electrodes is derived in this paper. That is Di = abkQTPX(K,vDE,b,t,d) were a is the electron transfer coefficient, its value is 0.5 ~ 1, b = D/d2(D is the diffusion coefficient in film, d is the film thickness), k is the constant of experiment, QTP is the charge of polymerisation, X is the function of these parameters K, v, DE, b, t, d, and is calculated numerically. The equation is verified already and experimental results are in good agreement with the theor.
