Abstract / Full Text

The use of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and 4-acetamido-TEMPO (ACT) for electrochemical oxidation of L-sodium lactate (SL) was comparatively investigated by cyclic voltammetry, and it was proved that ACT is more effective as a mediator in these electrocatalytic reactions. A comprehensive investigation of electrooxidation performance of ACT toward SL through investigating the effect of pH, concentration of SL, the sensitivity of SL using this electroanalytical method was calculated to be 2.78 μA cm–2/mM, the catalytic rate constant was determined to be 51.7 L/(mol s) by using chronoamperometry.
