Abstract: Polysulfone(PSF)-Fe3O4 composite ultrafiltration membrane was made by phase-inversion process.SEM,AFM showed that most particles distributing uniformly in the membrane and the mean surface roughness(RMS) was only 46.059 nm in the range of the scan areas 30μm×30μm.The puerarin and troxerutin ultrafiltration with the PSF-Fe3O4 composite membrane in different magnetic intensities were performed respectively.The change current of permeation with the intensity were different.In the puerarin ultrafiltration test,the permeation got to maximum in 0.2 T while in the troxerutin test,the permeation got to maximum in 0.4 T.The difference proves the novel idea that different objects can be separated with only a composite membrane in turn by controlling the magnetic field doable.
