Electrochemical Polymerization of Variamine Blue Film at Glassy Carbon Electrode and its Electrochemical Behavior

Abstract:

Variamine blue (VB) polymer coatings can be obtained by electrochemical polymerization at glassy carbon electrode. The electrochemical behavior of this stable polymer film at glassy carbon electrode was investigated by cyclic voltammetry. The surface coverage, Γ,the charge transfer coefficient, α , and the charge transfer constant, k_s, for electron transfer between VB and glassy carbon electrode were calculated as 9.0×́10^-5 mol·cm^-2, 0.47, 2.97 s^-1 respectively. This VB polymer coatings modified electrode shows good electrocatalytic activity toward ascorbic acid (AA), uric acid (UA). It can be used in simultaneous determination of AA and UA in a mixture.
