| Abstract: | In this study,the water-based ferromagnetic fluid and magnetic resin made from chitosan and cerium complex(MRCCC) were successfully prepared by using the chemical co-precipitation technique and by the reversed-phase suspension cross-linking polymerization.MRCCC presented uniform and narrow particle size distribution as determined by the Laser Particles Sizer.The Inductively Coupled Plasma-Atomic Emission Spectrometry(ICP-AES),Fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry(DSC)and X-ray powder diffraction(XRD)study demonstrated that there were iron and cerium existing in MRCCC.The movement of MRCCC under magnetic field proved its magnetic property.The swelling kinetics in water or solutions with different pH indicated that MRCCC could be applied in solutions with pH greater than 1.0.The ferromagnetic fluid particles were stable in MRCCC soaked in solutions with pH >2.0.In view of these results,MRCCC can be used as material for separation,clarification,adsorption,sustained release and hydrolysis activity. |
