Numerical simulation of alternating current linear sweep voltammetry at microdisc electrodes
DJ Gavaghan‚ DM Elton and AM Bond
Abstract
We extend our earlier work on the numerical simulation of ac linear sweep voltammetry at macroelectrodes to the case of microdisc electrodes. This requires the solution of the underlying diffusional transport equations in two dimensions, rather than one, using a cylindrical coordinate system. We use the two-dimensional FIRM algorithm combined with a specially designed exponentially expanding mesh. We examine the ac response as a function of the frequency and amplitude of the ac signal, and as a function of the non-dimensional parameter p = (nFa(2)v/RTD)(1/2), where a is electrode radius,
