The electrochemical oxidation of sulphite on gold electrodes

Abstract:

The electro-oxidation of sulphite is studied in acid media on gold macroelectrodes and Au particle array modified boron doped diamond electrodes. The sulphite oxidation proceeds through a one-electron transfer process followed by a chemical step of second order (EC2 mechanism), as evidenced by experimental voltammetry and digital simulation for both gold macroelectrodes and gold particle modified substrates. The diffusion coefficient of sulphite is calculated consistently for both cases at ab...
