چکیده انگلیسی
Na-doped WO3 nanorods were successfully prepared via a hydrothermal synthesis method and further characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). A novel and sensitive electrochemical sensor has been fabricated for determination of bisphenol A (BPA) based on the as-synthesized nanomaterials modified carbon paste electrode (CPE). Electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were applied to demonstrate the electrochemical performances of the Na-doped WO3 modified CPE (Na-doped WO3/CPE). By using the DPV technology, the linear calibration curve was obtained within a wide concentration range from 0.0810 μmol Lâ1 to 22.5 μmol Lâ1 with the low detection limit of 0.028 μmol Lâ1 (S/N = 3) for BPA. Moreover, the sensor also showed good anti-interference ability in the interference study and satisfactory recovery between 95.70% and 105.3% in the practical sample analysis. Thus, the proposed sensor could be advantageously employed for the determination of BPA in environmental science.
