摘要：A water-dispersible and supermagnetic nanocomposite (PAD-PEGFe(3)O(4)@PEI) has been successfully synthesized using polyethylenimine (PEI, Mol MW 10000) coated supermagnetic Fe3O4-NH2 which was modified with 2, 2'-(phenylazanediyl) diacetic acid (PAD) through the bridge of poly(ethylene glycol) (PEG, Mol MW = 2000). The average particle size of PAD-PEGFe(3)O(4)@ PEI was determined by TEM, and was about 50 nm. From magnetic hysteresis cycles for PAD-PEG-Fe3O4@PEI at room temperature, the saturation magnetization (Ms) was shown to be 58.14 emu g(-1). Inductively coupled plasma spectrometry (ICP) analysis showed that the designed magnetic nanocomposite can remove 98% and 80% of Cd2+ from water and blood, respectively.
