Reduced graphene oxide/iron oxide (GO/FeO center dot Fe2O3) composites were prepared as super adsorbent to adsorb 1-naphthylamine, 1-naphthol and naphthalene with different polaritiy. The adsorption capacity was found in the order of naphthalene < 1-naphthol < 1-naphthylamine. Electron-donor-acceptor (EDA) interaction was proposed to be the primary mechanism for the adsorption of aromatic compounds, and the adsorption capacity increased with increasing dipole moment. Compared with multi-walled carbon nanotubes/iron oxide (MWCNTs/FeO center dot Fe2O3), we found the morphology of adsorbents played an important role in the adsorption for these aromatic compounds. Thermodynamic experiments further indicated that the adsorption processes were endothermic and spontaneous. (C) 2012 Elsevier B.V. All rights reserved.
