摘要：
A paste electrochemical sensor, based on a Fe3O4 modified carbon paste electrode, has been developed for investigation of Bisphenol A (BPA) oxidation in phosphate buffer solution (PBS) pH 7. In this study, it figures out that Fe3O4 reveals the best electrocatalysis on oxidation of Bisphenol A at ratio of C powder/Fe3O4/parafine oil = 76/4/20. With this composition, the BPA oxidation current recorded is 1.70 times higher than that with no Fe3O4 in CPE. It is applicable to develop an electrochemical sensor with proper amount of Fe3O4 in the paste in order to enhancement the signals of BPA during its analysis.
