Voltapams of L-ascorbic acid on a gold electrode show the existence of two oxidation waves but no reduction wave. An analysis of the i-E curves was carried out together with the Tafel slopes and reaction orders. The products from the first oxidation were identified by paper chromatography. A scheme
## AbStl%Wt The determination of L-ascorbic acid by utilizing lucigenin chemiluminescence with ascorbate oxidase was studied. The dehydroascorbic acid produced by the enzymatic reaction of L-ascorbic acid and ascorbate oxidase was found to be a more effective activator than L-ascorbic acid for the
