Conducting polymer based modified electrode was employed for this investigation. The electrochemical techniques such as cyclic voltammetry, chronoamperometry and chronocoulometry were used to study the behaviour of the electrode under the condition of deaeration in the pH range 1.0 to 13.0. The diffusion coefficient value of anthraquinone and number of electrons involved in the anthraquinone reduction were evaluated from the chronoamperometric and chronocoulometric data’s.
