Abstract
The electrochemical study of Catechol (CC) was studied in presence of Hydroquinone (HQ) using poly(murexide) modified glassy carbon electrode (MGCE) by cyclic voltammetric study. The modified electrode exhibited good affirmative response towards the electro chemical oxidation of CC in presence of HQ in 0.2 M phosphate buffer solution at the physiological of pH 7.4. The influence of scan rate, concentration and pH parameters were examined with the cyclic voltammetric method. The modified electrode showed good selectivity and sensitivity with an advantage of interference study and free determination of selected analytes in this experiment. Finally a simple, sensitive and selective method was developed for the determination of dihydroxybenzene isomeric compounds.
