Abstract: The oxidation mechanism of sulfur dioxide on gold and ruthenium electrodes has been studied by chronopotentiometry, clironoamperometry and the steady-state method. The kinetic parameters in sulfur dioxide oxidation have been calculated and a possible oxidation mechanism has been proposed.

Key words: sulfur dioxide, gold electrode, ruthenium electrode, electrochemical oxidation, mechanism
