摘要：

The electrocatalytic characteristics of a poly(1-naphthylamine) film complexed with Ni(II) and Co(II) ions were studied by cyclic voltammetry, a.c. impedance analysis, X-ray photoelectron spectrometry and other methods. In a basic medium, the oxidation of ascorbic acid can be electrocatalysed by the chemically modified electrode. It is suggested that the electrocatalytic reaction of ascorbic acid is controlled by the diffusion of ascorbic acid. A possible model for the oxidation process of ascorbic acid is proposed. The applicability of the electrode was assessed by the determination of ascorbic acid in drugs.
