Monodisperse Pd nanoparticles (Pd NPs@CGO) decorated Chitosan-graphene oxide (CGO) are produced to get a nanoadsorbent material to remove methylene blue (MB) from aqueous solutions. X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS) were used to characterize the Pd NPs@CGO. The spectroscopic results showed that Pd NPs@CGO has highly crystalline, monodisperse and colloidal structures. Furthermore, Pd NPs@CGO was highly efficient and stable for methylene blue removal. They provide a high adsorption capacity of 186.42 mg/g and its MB adsorption equilibrium is obtained in similar to 60 min. Nonetheless, Pd NPs@CGO are reusable and promising nanocomposites for methylene blue removal, keeping 43.05 % of the first efficacy after six adsorption-desorption cycles.
