Simulation of Square Wave Voltammetry:  Reversible Electrode Processes

The Journal of Physical Chemistry B, 1999
A general approach is developed for the numerical simulation of square wave voltammetry (SWV) at uniformly accessible electrodes, based on the backward implicit method. Appropriate transformations of both the spatial coordinate normal to the electrode surface and of the time variable are developed and are shown to lead to efficient and accurate ...
