N2 - In this work, we developed a highly selective detection of chloramphenicol (CAP)using palladium nanoparticles decorated graphene oxide (rGO/PdNPs)nanocomposite. Moreover, the successful formation of rGO/PdNPs nanocomposite was verified by TEM, UV–Vis, FT-IR spectra, X-ray photoelectron spectroscopy (XPS). The electrochemical characteristics of the electrochemical sensor were evaluated by differential pulse voltammetry (DPV)and cyclic voltammetry (CV). Furthermore, the rGO/PdNPs modified GCE displayed an excellent electroactivity in the presence of chloramphenicol as compared to that of modified and unmodified glassy carbon electrode (GCE). It showed an excellent performance with a linear response range of 50–1000 nM and the low detection limit of 50 nM (S/N = 3). In addition, the present promising sensor exhibited high sensitivity, good stability as well as remarkable reproducibility, and satisfactory recovery rate for CAP electrochemical detection in real samples.
