Power ultrasound emitted from a titanium horn probe placed opposite a working electrode in a conventional three electrode cell was applied during the preconcentration step of the adsorptive stripping voltammetric analysis of a vanadium-catechol complex at a mercury-plated copper electrode. Ultrasound was found to significantly improve the sensitivity of the procedure by increasing the rate at which the complex was deposited onto the mercury surface in comparison with silent conditions. The adsorption appeared to follow a Langmuir isotherm. References 1 R. G. Compton, J. C. Eklund, F. Marken, Electroanalysis 1997, 9, 509, and references given therein. 2 D. J. Walton, S. S.
