英文摘要	In this study, dicyandiamide (DCDA) modified polystyrene (PS) resin beads decorated with nano-Fe3O4 (Fe3O4-PS-DCDA hybrids) were prepared by co-precipitation method. The Fe3O4-PS-DCDA hybrids were characterized by scanning electron microscopy (SEM), Fourier transform-infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) spectroscopy, X-ray photoelectron spectroscopy (XPS), nitrogen adsorption/desorption isotherms, and vibrating sample magnetometer (VSM). Meanwhile, the adsorption property of Fe3O4-PS-DCDA hybrids for Hg(II) in aqueous solution was investigated by batch methods. The results show that the nano-Fe3O4 decorated on the outer surface and interior of DCDA modified PS resin beads (PS-DCDA) is nanoparticles and nanorods, respectively. The saturation magnetization (Ms) of the Fe3O4-PS-DCDA hybrids is 0.70 emu/g, which is enough to ensure the convenient magnetic separation. The adsorption kinetics of the hybrids for Hg(II) accorded with the pseudo-second-order model and the adsorption isotherms followed the Freundlich equation. POLYM.
