▎ 摘　　要

In this paper, a graphene oxide nanocomposite decorated with silver nanoparticles (Ag@GO) was used to modify a glass carbon electrode (GCE) as a nonenzymatic electrochemical sensor for detecting carbofuran (CF) in vegetable samples. According to surface morphology and crystal structure studies utilizing FESEM and XRD, the porous shape of the Ag@GO nanocomposite was generated by adorning the pure crystalline nature of the Ag NPs on the surface of GO sheets,. DPV and amperometry were used to investigate the electrochemical properties of the Ag@GO/GCE, revealing that the modified electrode can be used as a comparable or better sensor for selective CF detection among the most commonly found compounds in real samples of fruits and vegetables than other reported CF sensors. According to the results, the modified electrode can detect CF in a wide detection range of 1 to 1000 mu M, with a lower detection limit of 10 nM. Furthermore, the Ag@GO/GCE was employed to determine CF in real celery and lettuce samples and displayed efficient sensing ability, demonstrating that the Ag@GO/GCE has outstanding CF determination accuracy in vegetables.
