摘要：

The electrochemical oxidation of bisphenol A has been studied by CdO nanoparticle ionic liquid carbon paste electrode. Cyclic voltammetry, square wave voltammetry, and chronoamperometry were used to investigate the suitability of new sensor for the electrooxidation of bisphenol A in aqueous solution. The electrooxidation of bisphenol A occurs at a potential about 50 mV less positive than with the unmodified carbon paste electrode at pH 7.0. The square wave voltammetry (SWV) peak currents of the electrode increased linearly with the corresponding bisphenol A concentration in the range of 0.3-650 mu M with a detection limit of 0.1 mu M. The influence of pH value and potential interfering substances on the determination of bisphenol A were studied. Finally, the proposed novel sensor was also examined as a sensitive, high selective, simple, and precise electrochemical sensor for the determination of bisphenol A in food samples.
