Under reversible conditions, this system simplifies to a situation that can be described by a convolution expression and can therefore be modelled by the method known as convolutive modelling. Convolutive modelling is here employed to simulate cyclic voltammograms at a disk electrode; those results are compared to fast quasi-explicit finite difference digital simulations. The inaccuracy of the latter method is thereby exposed. In addition, current reversal chronopotentiometry at a disk is modelled.Keywords: Algorithms; Computer simulation; Cyclic voltammetry; Electron transitions; Functions; Mathematical models; Problem solving; Chronopotentiometry; Convolutive modeling; Cope-Tallman method; Disk electrodes; Fast Quasi Explicit finite difference (FQEFD) simu Chronopotentiometry; Convolutive modelling; Cope-Tallman method; Cyclic voltammetry; Disk electrodes; FQEFD simulation200410.1016/j.electacta.2004.07.0182016-02-24
