Abstract :
In the present work, we describe the preparation of a glassy carbon electrode modified with thiourea and investigate its performance for the determination of EP in aqueous solutions. Differential pulse voltammetry (DPV) exhibits a linear dynamic range from 5.0×10-8 to 1.1×10?5 M and a detection limit of 2.3×10?8 M for EP. We also evaluate the analytical performance of the modified electrode for quantification of EP in real samples.
