The influential factors towards graphene oxides removal by activated carbons: Activated functional groups vs BET surface area-dataset

Two commercially available different activated carbons (ACs) were used as adsorbents for GO and methyl orange (MO, as a control) elimination. AC1 possesses more oxygen-containing functional groups, while AC2 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. AC1 exhibited a ~4 times higher removal GO efficiency than that of AC2 while AC2 adsorbed ~55 times of MO than AC1.
