Solution of equation for a current-voltage curve describing reversible metal electrodissolution with linear boundedly semi-infinite diffusion and a linear alteration of potential in the stripping voltammetry method

Abstract

An exact, sufficiently simple, explicit expression is obtained and a full contour of the stripping-voltammetry peak is calculated for a reversible process on a thin-film mercury electrode of finite thickness (linear boundedly semi-infinite diffusion is taken into account) in conditions of stripping voltammetry at a linearly altering potential. That these results were obtained at all, is due to use made of two extra boundary conditions (Nemov’s and Nazarov’s). The addends in the four forms of equations derived are the limiting expressions and “corrections” in the form of Nemov’s or Nazarov’s boundary conditions. It is shown that it is advisable to employ different forms of equations at large and small values of parameter H. The peak’s height, full width at half-maximum, and potential are found to depend on H.
