Abstract: The electrocatalysis characteristic of Ni-PNAchemically modified electrode was studied.Asimplex method was used for the experimental design.The cyclic voltammetry studies on PNAand Ni-PNAfilm were carried out.It was observed that the Ni-PNAfilm showed electrocatalysis for the oxidation of amino-acid and ascorbic acid in a basic medium.The CMEcan be used for determination of ascorbic acid.

Key words: Polynaphthylamine film, Chemical modified electrode, Ascorbic acid, Electrocatalysis
