| 摘 要： | 以相转化法制备了磺化聚砜(SPSF)/聚醚砜(PES)共混新型纳滤膜,并研究了磺化聚砜的磺化度以及聚醚砜/磺化聚砜的共混质量比对低分子量PEG的截留率和脱盐率性能的影响.结果表明:在操作压力为0.5MPa,料液温度为25℃下,当PES/磺化度10%SPSF共混比为6∶4时,SPSF/PES共混膜对PEG1000、PEG800和PEG600的截留率分别为99.8%、81.0%和57.8%,对硫酸钠、氯化钠的截留率分别为69.0%和23.5%,SPSF/PES共混膜的纯水通量为90.3L/(m2.h).

| Abstract: | Sulfonated polysulfone(SPSF)/Polyethersulfone(PES) blend nanofiltration membranes were prepared using a simple phase inversion technique.The performance of SPSF/PES blend nanofiltration membranes was systematically studied.The results showed that SPSF/PES blend nanofiltration membranes with the blend ratio of 6/4 of PES/10% sulfonation degree SPSF had high rejection of PEG1000(99.8%),rejection of PEG800(81%),rejection of PEG600(57.8%),rejection of Na2SO4(69%),rejection of NaCl(23.5%) and great water flux(90.3 L/(m2·h) at 0.5 MPa and 25 ℃. |
