Tarasova, V. Kiryushov] The oxidation of ascorbic acid (AA) was studied at the electrodes made of platinum, gold, and a graphite-epoxy resin composite. Cutting the surface electrode layer in situ in solution before each polarization activated the electrode surface. This activation manifested itself in a more negative potential of the AA anodic peak, a change in the current peak shape, and an increase in the current density at the electrodes as compared to the polished electrodes. The in situ renewal of electrodes allowed us to develop a rapid voltammetric procedure for determining AA at an electrode made of a graphite-epoxy resin composite in different samples. The analytical range for AA was 0.1-200 mg/L, the determination limit for AA was 0.05 mg/L, and the RSD was 3-5%. MAIK "Nauka/Interperiodica”, 2005 Tarasova V.
