| Abstract: | The polymeric heme film modified glassy carbon electrode (polyheme/GC) was prepared by cyclic voltammetry. The electrochemical behavior of catechols (catechol, dopamine, epinephrine) and ascorbic acid on the polyheme/GC electrode has been investigated. The polyheme/GC electrode has a good electrocatalytic oxidation to catechols and ascorbic acid. On the polyheme/GC electrode, the oxidation peak currents of catechols and ascorbic acid increase and the oxidation peak potentials of catechols and ascorbic acid shift negatively about 180 mV and 370 mV,respectively, comparing with that on the GC electrode. In the mixed solution containing catechols and ascorbic acid, the two oxidation peaks could be separated about 130 mV on the polyheme/GC electrode. |
