Abstract

The electrochemical oxidation of ascorbic acid(AA), serotonin(SE) and epinephrine(EP) have been performed at poly N,N-dimethylaniline(PDMA) film coated diamond electrode. This cationic polymer film is electrochemically deposited on boron-doped diamond electrode surface. Unlike the bard electrode, the polymer film-coated diamond electrode can well separate the oxidation potential of AA by 200mV. Thus this electrode can be successfully used for the simultaneoud detection of both species. Increases in the concentration of AA do not affect the reponse of EP and SE.
