Abstract

In this study Fe3O4 with addition of graphene materials were investigated as an adsorbent for removing organic dye from the aqueous solution. Fe3O4-graphene were synthesized using hydrothermal method. The contents of graphene were varied from 5, 10, and 15 weight percent (wt%). Their physical properties were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and surface area analysis. The cubic spinel of the samples was detected which attributed to the existence of Fe3O4 materials. The removal of organic dye was investigated using adsorption process. Methylene blue was selected as a model of organic pollutant. Their kinetic reaction indicates that the samples follow the pseudo second order kinetic reaction with maximum adsorption capacity was 48 mg/g. The samples performed good stability for removing methylene blue using adsorption process with 95 % efficiencies.
