摘要：C8-modified magnetic graphene oxide (C8-MGO) was synthesized and characterized using Fourier transform infrared spectroscopy and transmission electronic microscopy. The C8-MGO was applied to the adsorption of di-(2-ethylhexyl) phthalate (DEHP) from aqueous solution, and the adsorption performance was examined. The experimental results indicated that the sorption equilibrium was achieved within 2.5 h, the adsorption capacity was 2.5 mg/g, and the adsorption process could be well described by Freundlich isotherm model and pseudo-second-order kinetic model. There are π–π interaction, hydrogen-bond interaction and hydrophobic interaction of C8-MGO with DEHP. The prepared C8-MGO can be a potential sorbent for removal of DEHP at low levels from aqueous solution.
