Abstract
The optimal value of sampling parameter that guarantees the global equivalence of staircase and linear scan voltammograms plotted for electrochemical reactions involving soluble species is re-examined in this second article taking the electron transfer kinetics, the uncompensated resistance and the double-layer charging current into account. The discussion is based on the numerical solution of linear/nonlinear integral-equation-based models. The comparison of voltammetric and staircase voltammetric current data is carried out in terms of the mean squared deviation between voltammograms. Main results concern the dependence of the optimal sampling parameter on the potential step amplitude of staircase signal, and the dimensionless parameters pertaining to kinetic, Ohmic and capacitive effects.
