▎ 摘　　要

In this work, a magnetic graphene oxide-based molecularly imprinted polymers (GO-Fe3O4-MIPs) was prepared for selectivity recognition and separation of diethylstilbestrol (DES). The prepared composite was evaluated and characterized in detail by transmission electron microscopy, X-ray diffraction, Fourier-transform infrared spectra, and vibrating sample magnetometer analysis. The results showed that this hybrid had a saturation magnetization value of 5.60 emu g(-1), which provided an efficient way to separate toxic pollutants from extreme environments. Batch mode adsorption showed the Langmuir isotherm model and the pseudo-second-order equation were well fitted to the adsorption of GO-Fe3O4-MIPs hybrids. The selectivity recognition experiments demonstrated the GO-Fe3O4-MIPs possessed excellent adsorption capacity for DES (2183 mu mol g(-1) at 298 K), and outstanding selectivity for DES over the other competitive compounds.
