The rGO-Fe3O4-ZnOMIP/CPE shows a sharp and well-defined peak for the oxidation of BPA at 648 mV in Britton-Robinson universal buffer solution pH = 6.5. The presented electrode shows a dynamic range of 0.008-15 and 15-95 μM with the low detection limit of 0.004 μM. The repeatability, reproducibility, and stability of rGO-Fe3O4-ZnOMIP/CPE were checked and the obtained data confirm the excellent properties of the sensor. The selectivity of the presented method was investigated and the data show that Hydroquinone, Tert-butyl hydroquinone, Catechol and Bisphenol S and common ions had no disturbance on the detection of BPA and the changing in peak current was below 5%. Finally, rGO-Fe3O4-ZnOMIP/CPE was successfully applied for the determination of BPA tap water, food storage container and cured vinyl ester resin samples with satisfactory results.
