Determination of Carbendazim by Adsorptive Stripping Differential Pulse Voltammetry Employing Glassy Carbon Paste Electrode Modified with Graphene and Amberlite XAD 2 Resin

Graphene nanosheets (GNS) and amberlite XAD‐2 (XAD2) modified glassy carbon paste electrode (GNS‐XAD2‐GCPE) were fabricated for voltammetric determination of Carbendazim (MBC). GNS was synthesized by Hummer’s method and characterized by SEM, EDAX, and XRD techniques. After optimizing the analytical conditions in 0.4 M citrate buffer (pH 4.0), the peak current was found to be linear in the range of 8.36×10−9 to 4.13×10−6 M (r=0.9986) with detection limit of 3.14×10−9 M (S/N=3) by AdSDPV. The method was validated for the determination of MBC in soil, fruit, blood serum, urine, waste and ground water samples with satisfactory recoveries.
