Abstract
A simple and highly selective electrochemical method for the investigation of catechol (CC) and hydroquinone (HQ) was developed on the surface bare carbon paste electrode (BCPE) modified with electropolymerized thin film of o-Phenylenediamine (o-PD) by using cyclic voltammetric technique. Electrochemical measurements were carried by using both cyclic voltammetric (CV) and differential pulse voltammetric (DPV) techniques at poly(o-PD) modified carbon paste electrode (MCPE). The proposed modified electrode shows adsorption-controlled process and exhibited a good limit of detection for CC and HQ was 1.1 and 2.1 µM respectively. In order to study the selectivity of the electrode, interference study was carried out by using DPV technique. Therefore, poly(o-PD)/MCPE showed excellent electrocatalytic behavior for the simultaneous electrochemical investigation of CC and HQ
