ABSTRACT
Carbendazim (CBZ) insecticides have been widely employed, raising serious concerns about their impacts on human health and the environment. A facile hydrothermal technique was used to prepare a zinc ferrite (ZnFe2O4) combined with porous graphene oxide (PGO) as a nanocomposite for selective CBZ detection. The ZnFe2O4/PGO nanocomposite was then used to modify a glassy carbon electrode (GCE), an affordable platform for CBZ detection. Various spectroscopic techniques were employed to confirm the nanomaterial. The electrochemical properties were further investigated using cyclic voltammetry (CV), differential pulse voltammetry (DPV), and electrochemical impedance spectroscopy (EIS). The ZnFe2O4/PGO nanocomposite modified the glassy carbon electrode surface for CBZ detection. A broad linear response range of 0.0039 to 200 µM, high sensitivity (2.184 µAµM-1 cm-2), a low detection limit of 0.0013 µM, outstanding stability, repeatability, and practical applicability are the intriguing qualities of the ZnFe2O4/PGO-modified electrode for CBZ detection.
