Abstract

In the present work, we report a new method for facile and effective synthesis of poly (biphenol/biphenoquinone- vanadium (IV)) (poly BP/BQ-VIV) for the first time. The poly BP/BQ-VIV was applied for modification of a carbon past electrode (CPE/ poly BP/BQ-VIV) to enhance the electro-catalytic activity towards electro-oxidation of 4-nitrophenol (4-NP) molecules in solutions. The structure and the properties of the synthesized poly BP/BQVIV were characterized by various techniques such as FESEM, TEM, EDX, FT-IR, UV–Vis, XPS analysis, cyclic voltammetry, differential pulse voltammetry and electrochemical impedance spectroscopy. The CPE/poly BP/ BQ-VIV electrochemical sensor, exhibits a well-defined anodic peak for 4-NP molecules at 1.18 V vs. Ag/AgCl reference electrode. Under optimum experimental conditions, the CPE/ poly BP/BQ-VIV electrochemical sensor, shows a low detection limit of 60 nM, current sensitivity of 0.997 μA μM???? 1 and a linear response in the concentration range of 0.05 to 200 μM for quantitative measurement of 4-NP in aqueous solutions. The results verify that the CPE/ poly BP/BQ-VIV presents excellent reproducibility, appreciable repeatability, satisfactory stability, and high selectivity for detecting of 4-NP in tap and river water samples.
