The preparation of gold nanoparticles-reduced graphene oxide-based sensor materials for the determination of zinc(II)
dimethyldithiocarbamate (ziram) is described in this paper. The graphene oxide (GO) was synthesized using a modified
Hummer’s method. A composite sensor consisting of gold nanoparticles (AuNPs) and reduced graphene oxide (RGO)
was electrochemically fabricated on a glassy carbon electrode. The nanocomposite was evaluated utilizing scanning electron microscopy (SEM). Cyclic voltammetry was used to illuminate the modified sensor’s electrochemical properties at
each stage of the modification. The suggested sensor was demonstrated good analytical performance to determine ziram
pesticide in water and peach juice, including a very low detection limit, a large linear range, and a low RSD.
