▎ 摘　　要

The magnetite graphene nanocomposite (G/Fe3O4) obtained from banana peels was prepared via a simple and green technique and utilised as an environmental-friendly adsorbent for ce?xime(CFX) removal. The G/Fe3O4 nanocomposite was characterised by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometry (VSM), atomic force microscopy (AFM), Brunauer, Emmett, and Teller (BET), and UV-visible spectrophotometer. The adsorption parameters, including the initial CFX concentration, contact time, solution pH, temperature, and adsorbent dosage, were investigated. The adsorption kinetic and isotherm were well fitted by the pseudo second-order and Langmuir models, respectively. The results showed that the maximum adsorption capacities of CFX on G/Fe3O4 nanocomposite was 285.71 mg g(-1) andBET surface area of G/Fe3O4 nanocomposite was1905.5 m(2) g(-1).
