عنوان انگلیسی Highly Sensitive Endocrine-Disrupting Chemicals Pollutants Detection on ZnO Enhanced Nano Carbon Electrode
چکیده انگلیسی مقاله An innovative investigation was conducted to characterize a Zinc Oxide-modified nano carbon (NC-ZnO) electrode for the development of an initial model for detecting Endocrine-Disrupting Chemicals (EDCs). NC-ZnO synthesis was carried out by the hydrothermal method and characterized. The particle size of the carbon-modified ZnO is determined to be 22.85 nm. The electrochemical performance evaluation demonstrates that the ZnO modification significantly improves electron transfer and enhances the electrochemical performance of NC electrodes in terms of increased peak currents and narrower current peaks. The results of our study indicate that the NC@ZnO composite electrode is effective in detecting fipronil, with efficient electron transfer occurring at a low oxidation potential. Additionally, the electrode demonstrates a highly linear sensitivity to fipronil concentration in the range of 10 to 10-3 µg/L, and it boasts an impressive limit of detection (LoD) of 0.00393 µg/L. Moreover, the NC@ZnO composite electrode shows exceptional stability in detecting fipronil, as evidenced by the low stability coefficients of %RSDR (0.048) and %PRSDR (0.13). These findings suggest that the newly developed NC@ZnO composite electrode holds great promise as a sensitive tool for detecting fipronil in the environment, thus potentially helping to reduce its negative impacts on human health and ecosystems.
