摘要：
This paper presents a simple and low-cost approach to synthesizing reduced graphene oxide/clay modified pencil electrode (rGO/Clay/PGE) through thermal reduction of GO/Clay for ultrasensitive detection of Flubendiamide (FBD). The graphene oxide (GO) was prepared by exfoliation of graphite with an eco-friendly procedure. The as-produced rGO/Clay was characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), and Scanning electron microscopy (SEM). The elec-trochemical behavior of the synthesized electrode was studied by cyclic voltammetry (CV). Under optimized conditions, rGO/Clay/PGE exhibited excellent analytical properties toward FBD determination. A calibration curve was well-established from 0.1 to 100 mmol/L for FBD with a detection limit of 0.006 mmol/L. The method was successfully adopted for the detection of FBD in white rice samples.(c) 2022 Elsevier Ltd. All rights reserved.
