英文摘要	In this work, the magnetite/sepiolite (M/SEP) composite was synthesized by chemical co-precipitation method and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and vibrating sample magnetometer (VSM). The characterization results showed that M/SEP was composed of magnetite and sepiolite and had a superparamagnetic property. Considering the good separation characteristic after use, M/SEP composite was used as a sorbent for the removal of Co(II) and Cd(II) from aqueous solutions. The pH and temperature on Co(II) and Cd(II) sorption to M/SEP composite were investigated. The results showed that the sorption of Co(II) and Cd(II) was strongly dependent on pH, and the Langmuir sorption capacities of M/SEP composite for Co(II) and Cd(II) were 18.85 and 14.15 mg/g at 20 degrees C, respectively. The thermodynamic parameters indicated that the sorption processes of Co(II) and Cd(II) on M/SEP composite were endothermic and spontaneous processes. Herein, this finding suggests that M/SEP composite can be applied on the preconcentration of heavy metal ions in the field of water treatment. (C) 2015 Taiwan Institute of Chemical Engineers.
