摘要：
Nanoparticulate metal oxides have attracted a lot of interest because of their improved characteristics brought about by their downsizing. An effective combustion process was used in this study to create zinc oxide nanoparticles (ZnO NPs), which were then functionalized with reduced graphene oxide (RGO) to create a nanocomposite. The materials were thoroughly characterized utilizing methods like scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and powder X-ray diffraction (PXRD). Glassy carbon electrodes (GCE) were modified using the resultant ZnO/RGO nanocomposite to enable the sensitive electrochemical detection of trace lead (Pb (II)) ions in environmental samples. Excellent electrochemical performance of the redesigned electrode was demonstrated by differential pulse anodic stripping voltammetry (DPASV) and cyclic voltammetry (CV). The sensor showed a linear response for Pb (II) concentrations between 10 and 90 ppb, with a detection limit of 7 ppb. This innovative sensor offers a viable platform for dangerous metal environmental monitoring.
