Abstract:A systematic study on the behavior of a chemically modified electrode with poly(1-naphthylamine) membrane complexed with various metal ions,such as silver,mercury etc. is described. The electro-catalytic characteristics of the Ag-PNA electrode to the oxidation of ascorbic acid have been studied by cyclic voltammetry,a. c. impedance analysis and other methods. It is suggested that the electro-catalytic reaction of ascorbic acid is controlled by diffusion. A possible mechanism for the ascorbic acid oxidation is proposed. The Ag-PNA electrode can be used for the determination of ascorbic acid in pharmaceutical samples.
Keywords:Chemically modified electrode  Poly(1-naphthylamine) membrane
