Abstract
The electrochemical oxidation of ascorbic acid(AA), serotonin(StT) and epinephrine(EP) have been performed ae poly N,N-dimethylanliline(PDMA) film coated diamond electrode. This cationic polymer film is electrochemically deposited on boron-doped diamond electrode surface. Unlike the bard electrode, the polyaer film-coated diamond electrode can well separate the oxidation potential of AA by 330mV. Thus this electrode can be successfully used for the simultaneoud detection of both species. Increases in the concentration of AA donot affect the reponse of EP and ST.
