Abstract : An imprinted electrochemical sensor based on modified glassy carbon electrode (GCE) for ultrasensitive detection of 4-chlorophenol (4-CP) was fabricated. A GCE was modified by zinc oxide nanoparticles/graphene nanoplatlets/poly(o-phenylenediamine) polymer nanocomposite (ZnO/GNPs/PoPD/MIP), and the results revealed the nanocomposite improved the electrochemical response and sensitivity of the sensor for the detection of 4-CP. The surface morphology and crystal structure of prepared nanomaterials has been characterized using different chemical and physical techniques, which showed the homogenous distribution of the ZnO, and GNPs over the electrode. The electrochemical behaviors of the ZnO/GNPs/PoPD/MIP nanocomposite based sensor were evaluated through cyclic voltammetry and electrochemical impedance spectroscopy. Under the optimization experimental conditions, the electrochemical sensor exhibited excellent analytical performance with very low detection limit. The sensor was applied to determine 4-CP in real water samples, and the sensor showed high selectivity, good sensitivity and excellent reproducibility. Finally, the results showed that ZnO/GNPs/PoPD/MIP based sensor could be a facile, robust, practical, low-cost and rapid tool for the potential on-line monitoring of 4-CP in water.
