Abstract :
The poly (congo red) film was developed on the surface of carbon paste electrode by electrochemical method. The fabricated poly (congo red) modified carbon paste electrode exhibited excellent electrocatalytic activity towards the oxidation of catechol (CC) and hydroquinone (HQ) in a binary mixture by cyclic voltammetric (CV) and differential pulse voltammetric (DPV) techniques. The scan rate effect was found to be adsorption controlled electrode process. The interference study was done by varying the concentration of one species while other kept constant. Overall a sensitive and selective method was developed for the electroanalysis of CC and HQ.
