✦ Synopsis

The electrochemical behaviour of the V(III)/V(II) redox couple has been investigated at glassy carbon electrodes using cyclic voltammetry. The oxidation/reduction is found to be electrochemically irreversible with a value k" = 1.2 X 10m4 at pH = 4. A slight trend in k" with pH is observed. Electrode poisoning effects are observed at the glassy carbon electrode, and surface preparation is found to be critical in determining observed behaviour.

The V(V)/V(IV) redox couple system has been studied at glassy carbon and gold electrodes in sulphuric acid solutions, using both cyclic voltammetry and rotating disc voltammetry. The system exhibits electrochemical irreversibility at a glassy-carbon surface with a value of k" = 7.5 X 10s4 cm 6'. The
