Our effort to develop a cyclic voltammetry (CV) simulator was generated by the need for a simple and manageable way to analyze complex electrochemical responses. A cyclic voltammogram is a complicated, time-dependent function of a large number of physical and chemical parameters. Until now there has been no effective computational tool for describing the cyclic voltammetric responses for a wide range of mechanism - at least not without a lot of ad hoc adjustments. The simulator has already shown promise as a tool for teaching the fundamentals of CV in particular and of electrochemistry in general (75). The movielike presentation of concentration profiles as they evolve with time in response to the changing electrode potential offers additional insights into the physical and chemical phenomena controlling the cyclic voltammetric response. Expanding the capabilities of the simulator to include finite diffusion, the Frumkin effect, Marcusian heterogeneous kinetics, adsorption, disk and brand geometries, and some electroanalytical protocols in addition to CV should enhance its applicability. 75 refs., 6 figs.
