A novel adsorbent, cerium oxide modified graphene was synthesized for brilliant blue dye removal from aqueous solution. The morphology, chemical structure of the nanocomposite were characterized by X-ray diffraction (XRD) and Scanning electronic microscope (SEM). Adsorption of brilliant blue dye onto Graphene Oxide – Cerium Oxide was investigated with respect to pH, adsorption time, initial brilliant blue dye concentration and temperature. Kinetics data and adsorption isotherm, obtained at the optimum pH 6.3 for brilliant blue, were better fitted by pseudo-second-order kinetic model and by Langmuir isotherm [1-4].
