英文摘要	In this study, using graphene oxide (GO) as carrier, ferrous sulfate heptahydrate (FeSO4·7H2O) and ferric chloride hexahydrate (FeCl3·6H2O) as iron sources, sodium hydroxide (NaOH) as precipitant, β-cyclodextrin (β-CD) as a modifier, β-cyclodextrin modified magnetic graphene oxide (β-CD/MGO) nanohybrids were fabricated by a simple one-step reverse phase co-precipitation method. The as-prepared β-CD/MGO nanohybrids were characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), N2 adsorption/desorption isotherm, X-ray photoelectron spectroscopy (XPS) and Zeta potential analysis. Simultaneously, the adsorption properties of the β-CD/MGO nanohybrids for Pb(II), Cu(II) heavy metal ions and methylene blue (MB) in single aqueous solution were explored by batch experiments. The results revealed that the β-CD/MGO nanohybrids with high superparamagnetism were successfully fabricated, the maximum adsorption capacities of β-CD/MGO nanohybrids for Pb(II), Cu(II) and MB were 279.21, 51.29 and 93.97 mg·g−1 at 298 K, respectively. The adsorption process could be better fitted by pseudo-second-order model and Langmuir model. © 2018 Elsevier B.V.
