نویسندگان
چکیده
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 surface was performed by dispersion drop-casting. electrochemical behavior evaluated cyclic voltammetry (CV). oxidation peak observed during anodic potential scan at potentials 0.45 V. Higher currents (Ipa) were Fe3O4/GO/GCE than bare GCE. electrochemical differential pulse (DPV) revealed linear response in concentration range 1.0×10-7 to 5.0×10-5 M, detection limit 9.0×10-8 M. method successfully applied water samples, good recoveries.
