Abstract:

In this paper, a new method for preparing Silver-Mercury(film) Microring Electrodes (SMRE) by chemical plating is presented. The cyclic voltammetric responses of benzoquinone on SMRE have been studied in detail. The results show that the reduction of benzoquinone in Mcllvaine buffer(pH=7.0) is a one-electron reversible reaction. Values of n and D0 determined agree with those obtained by other electrochemical methods found in literature.
