Abstract In this study, graphene nanosheets (GNS) produced from electrochemical exfoliation of graphite rods were directly employed for removing of arsenic (As(III)) from aqueous solution. The properties of GNS were characterized by scanning electron microscopy, tunneling electron microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. By applying Langmuir adsorption isotherm, the maximum adsorption capacity was calculated to be 25.84 mg/g, which is relatively high due to the effective interaction of As(III) and oxygenated functional groups available on the surface of as-prepared GNS.
