| 英文摘要 | With popular development and usage of graphene oxides (GO), GO may be discharged into environment and probably cause environmental contaminations. In this work, two commercially available different activated carbons (ACs) were used as adsorbents for GO and methyl orange (MO, as a control) elimination. AC(1) possesses more oxygen-containing functional groups, while AC(2) has much larger Brunauer-Emmett-Teller (BET) surface area. The external factors towards GO removal by ACs were systematically investigated via batch experiments, including the contact time, ionic types and concentration, pH value, temperature. AC(1) exhibited a similar to 4 times higher removal GO efficiency than that of AC(2) while AC(2) adsorbed similar to 55 times of MO than AC(1), indicating activated functional groups on the surface of ACs played an important role in the GO adsorption on ACs and BET surface area of ACs was the key factor in the adsorption of MO on ACs. Commercial ACs with more functional groups would be a promising material for the efficient removal of GO from wastewater. (C) 2018 Elsevier B.V. All rights reserved. |
