Cyclic voltammetry, chronoamperometry and differential pulse voltammetry (DPV) techniques were used to investigate the modified electrode for the electrocatalytic oxidation of (EP) and (AC) in aqueous solutions. The separation of the oxidation peak potential for EP- AC was 200 mV. Under the optimum conditions, the calibration curve for EP was obtained in the range of 1.0 to 25.0 µM and 25.0 to 500.0 µM. The diffusion coefficient for the oxidation of EP at the surface of modified electrode was calculated as 5.76×10-5 cm2s-1.}, keywords = {}, url = {https://tips.sums.ac.ir/article_42260.html}, eprint = {https://tips.sums.ac.ir/article_42260_dbc52bbf52dbf81060bd6a71c19d9e92.pdf} }
