| Gaia: | Abrasive stripping voltammetry, using chemical vapour deposition (CVD) diamond electrodes and reference substrates comprising silver and tin, has been investigated. The abrasion process produced metallic particulates on the electrode surface, and both the mechanical and electrical contact were sensitively dependent on the abrasive force used. Only a small fraction of the material transferred was removed during electrochemical stripping. The silver deposited yields an analytically diagnostic signal in stripping voltammetry; data for tin was found to be extremely dependent on the stripping conditions employed. The initially hydrogenated diamond electrodes were shown to become significantly oxidised when employed in this application. © 2002 Elsevier Science B.V. All rights reserved. |
