Sensitive Electrochemical Analysis of Resorcinol using Polymer Modified Carbon Paste Electrode: A Cyclic Voltammetric Study

Glycine was electropolymerized on a carbon paste electrode (CPE) to form the polymer film in the electrooxidation process of the amino and carboxylic group containing compound by cyclic voltammetric technique and the electrochemical oxidation of resorcinol (RC) was studied in 0.2 M phosphate buffer solution (PBS) having pH 7.0. Modified carbon paste electrode (MCPE) shows a good electrocatalytic activity towards RC compared to bare carbon paste electrode (BCPE). The oxidation of RC at MCPE showed a linear relation versus concentration of RC in the range of 6×10-5 to 1×10-3 M with a detection limit 8.6×10-6 M.
