The application of fast-scan cyclic voltammetry methods to the high-speed microband channel electrode (Rees et al. J. Phys. Chem. 99 (1995) 7096) is reported. Theory is presented to simulate cyclic voltammograms for a simple electron transfer under high convective flow rates within the high-speed channel. Experiments are reported for the oxidation of 9,10-diphenylanthracene (DPA) in acetonitrile solution containing 0.10 M tetrabutylammonium perchlorate (TBAP) for both 12.5 and 40 gm platinum microband electrodes using a range of scan rates from 50 to 3000 V s(-1) and centre-line flow velocities from 12 to 25 m s(-1). Analysis of the voltammograms yielded values for k(0) and alpha for DPA which were measured to be 0.80 +/- 0.27 and 0.52 +/- 0.07 cm s(-1), respectively. The range of applicability of this method was also investigated. Experiments are also presented using steady-state linear sweep voltammetry to obtain accurate measurements of the heterogeneous kinetic parameters for DPA at a platinum microband electrode. The measured value of k(0) for DPA was found to be 0.94 +/- 0.16 cm s(-1), with alpha = 0.53 +/- 0.02 and a formal oxidation potential of 1.40 +/- 0.01 V (vs. Ag).
