Direct oxidation of ascorbic acid at an edge plane pyrolytic graphite electrode: A comparison of the electroanalytical response with other carbon electrodes

Abstract:: The direct electrochemical oxidation of ascorbic acid at an edge plane pyrolytic graphite electrode (EPPG) is investigated and compared with other common carbon-based electrodes, specifically glassy carbon, boron doped diamond and basal plane pyrolytic graphite. It is found that the EPPG electrode shows a significantly higher degree of electrochemical reversibility than the other electrode substrates giving rise to an analytically optimized limit of detection and sensitivity of 7.1 × 10-5 M and 0.065 A M-1 respectively.
