| 摘 要： | 用紫外光引发自由基共聚接枝的方法对酚酞基聚芳醚酮(PEK-C)超滤膜表面进行改性制备了亲水性荷电纳滤膜. 研究了用不同单体接枝改性膜对盐溶液的截留性能, 证明了Donnan电荷效应对纳滤膜分离性能的影响. 在此基础上, 通过丙烯酸(AA)与对苯乙烯磺酸钠(SSS)的共聚接枝, 并改变它们在接枝液中的相对含量, 成功地制备出膜的表观截留率和渗透通量都较高的纳滤膜.

| Abstract: | A novel hydrophilic charged nanofiltration membrane was prepared via UV irradiation graft po-lymerization on the polyetherketone-cadro (PEK-C) ultrafiltration membrane. The influence of grafting monomer nature on the salt rejection of the membrane showed the effect of Donnan interaction on the mem-brane performances in nanofiltration. Based on this phenomenon, graft copolymerization with sodium styre-nesulfate (SSS) and acrylic acid (AA) has been applied to the modification of PEK-C membranes. By ad-justing the molar ratio of the monomers a nanofiltration membrane with higher performance has been ob-tained. |
