A square wave voltammetric waveform (SWV) was applied to an inlaid microdisk electrode in a solution of K-4[Fe(CN)(6)]. A simple model relying on the assumption of steady state current throughout the scan was used to model the Current potential behaviour. However, experimental peak current magnitudes were between 30% and 50% greater than those predicted by the model. The model predicts an increase of peak current and peak width at half height with pulse height E-sw and frequency f, and non effect of the step height, Delta E-s. Experimental peak current magnitudes were found to increase with increasing E-sw but were not affected by f or Delta E-s. (C) 2008 Elsevier B.V. All rights reserved.
