【 摘 要 】

A new voltammetric sensor is proposed for the determination of bisphenol A, using a glassy carbon electrode (GCE) modified with Fe3O4/graphene oxide (GO) nanocomposite. The modification of the electrode surface was performed by dispersion drop-casting. The electro­chemical behavior of bisphenol A was evaluated by cyclic voltammetry (CV). The oxidation peak was observed during the anodic potential scan at potentials of 0.45 V. Higher anodic peak currents (Ipa) were observed at Fe3O4/GO/GCE modified electrode than at bare GCE. The elec­trochemical determination by differential pulse voltammetry (DPV) revealed a linear response in the concentration range of 1.0×10-7 to 5.0×10-5 M, with a detection limit of 9.0×10-8 M. The proposed method was successfully applied using water samples, with good recoveries.
