Abstract：

The CA/PSf blend membrane were prepared through the method of non- solvent phase separation (NIPS) by using polysulfone as membrane material, cellulose acetate (CA) as additive, N, N-dimethyl acetamide (DMAc) as solvent and deionized water as coagulation bath. The effects of different solid contents and mixture ratio of casting solution and different composition of coagulation bath on the microstructure and performances of blend membrane were investigated. The result shows that :compared with the traditional blending membrane that using polyvinylpyrrolidone (PVP) as additive, the dissolution of organic compounds in the blend membranes was greatly reduced by using CA as additive; The porosity is positively correlated with the solid content, but negatively correlated with the contents of CA. In addition, the water contact angle of the membrane decreases gradually with the increase of CA content. The pure water flux of blend membrane decreases continuously with the increase of solvent content in the coagulation bath, meanwhile, the retention of BSA solution increases gradually, and the membrane morphology become denser.
