A magnetic ultrafiltration membrane whose molecular weight cut-off(MWCO) can be between 31000 and 73000 under 0.2 MPa pressure and varying magnetic field intensity was prepared by in situ synthesis on the basis of a polysulfone ultrafiltration membrane with a MWCO of 80000 and used sequentially separate Angelica sinensis root polysaccharides with a purity of 97.5%.As a result,three fractions were obtained under various magnetic filed intensities and named as A,B and C,respectively.Their… CONTINUE READING
