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.
