The stoichiometry of the formation of hydrogen peroxide from ascorbic acid in a model wine system has been examined by square-wave voltammetry (SWV) on a hanging mercury drop electrode. Both ascorbic acid and hydrogen peroxide could be determined in the same test sample by first employing an anodic
