Abstract

---

In this study, graphene oxide (GO), produced using the modified Hummer’s method, (rGO) produced using ultra violet light. (rGO / Fe3O4) composite prepared by hydrothermal method. and it`s used as adsorbent to remove Alizarin Red S (ARS) dye from aqueous solution. Characterizations using Field emission scanning electron microscopy (FE-SEM) , powder X-ray diffraction (XRD) , FTIR , energy dispersive X-ray spectroscopy (EDX) were carried out on the rGO / Fe3O4 before the ARS adsorption experiments. The adsorption isotherms studies were conducted under different conditions (pH = 3-11, ARS concentration = 5-40 mg/L and Weight of composite= 0.005-0.25 g ) to examine the adsorption efficiency of the rGO / Fe3O4 towards ARS in aqueous solution. The obtained results showed that the maximum adsorption capacity of the rGO / Fe3O4 towards ARS can achieve up to ~0.1g for the adsorption at 10 mg/L ARS at 50 C. and the maximum adsorption capacity of the rGO / Fe3O4 towards ARS can achieve up to pH=7 and 0.25 g for composite.
