摘要: Magnetic microspherical β-cyclodextrin(CD)/Fe3O4@polyvinylpyrrolidone(PVP) particles, in which embedded Fe3O4 particles were coated by β-CD/glutaraldehyde crosslinked PVP, were synthesized via electrostatic spray and thermal crosslinking technologies. The magnetic microspheres were characterized by infrared spectroscopy, X-ray diffraction, scanning electron microscopy(SEM) and magnetic measurements, and the adsorption performance of the β-CD/Fe3O4@PVP composite nanoparticles for methyl orange was studied. The results show that the β-CD/Fe3O4@PVP microspheres could be quickly separated from the adsorption system under an external magnetic field within 30 s and that the adsorption capacity of the microspheres for methyl orange reaches greater than 90%, with a maximum adsorption quantity of 47.62 mg/g.
