In the present paper, the synthesis of reduced graphene oxide modified by magnetic iron oxide (Fe3O4/rGO) and its application for arenate (As(V)) removal  were demonstrated. The obtained samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and magnetic measurement. The results showed that the obtained graphene oxide (GO) consisted of a small part of initial graphite as well as reduced oxide graphene. The iron oxide in magnetic iron oxide was dispersed successfully over rGO. Fe3O4/rGO exhibited super-paramagnetic properties at room temperature. The formal kinetics and adsorption isotherms of As(V) over obtained Fe3O4/GO have been investigated. Fe3O4/rGO exhibits excellent As(V) adsorption indicating that it is an potential adsorbent for water sources contaminated by Arsenic.
