A new type of ultrafitration membrane with small molecular weight cut-off (MWCO), with PSF, with DMAC, with polyvinyl pyrrolidone (PVP) and FeCl2 as its raw materials, is prepared by means of the phase inversion method. The morphology of the membrane is controlled by adjusting the temperature of the casting solution, the temperatures of the coagulation bath and the support layer of membrane. The prepared ultrafitration membrane intercepts the matter of molecular weight: 2000-10000 with the interception rate of PEG of over 90% under the controlled process condition.
