  1. 文献调研及实验方案设计 报告人: 刘 媛 日 期:2013/09/14

  2. 文献调研 Using Journal of Membrane Science 381 (2011) 81–89

  3. 文献调研 Cleaning Alkaline cleaning Acid cleaning Organic foulants, inorganic colloids Precipited salts Separation and Purification Technology 63 (2008) 251–263

  4. 文献调研 Angewandte Chemie International Edition 2008, 120, 6108 –6113 sulfonated poly(arylene ether sulfone)s Excellent chlorine resistance PH stable Sulfonated aromatic polymers sulfonated polysulfones 磺化芳香族聚合物不仅可以保持聚合物本身的物理机械性能,而且提高了聚合物的亲水性,使得膜材料的水透过率和抗污染能力增加;提高了膜表面的负电荷密度,使膜具有一定的截盐能力;同时膜的耐氯和耐pH性能也显著增强。 sulfonated polyethersulfone (PES)

  5. 文献调研 。 Desalination 318 (2013) 56–63

  6. 相转化后处理制备纳滤膜 空气中干燥 48h 水相中 润湿 48h 相转化后处理法制备Pluronic F127/PES纳滤膜,不仅方法简单,而且使膜保持原膜典型的非对称结构,以及相应的抗污染性能。 高分子不可逆收缩,使得膜孔减小,对小分子形成了空间位阻效应 Pluronic F127/PES纳滤膜断面图 Industrial and Engineering Chemistry Research 2011, 50, 4678–4685

  7. 实验方案设计 铸膜液 脱泡 刮膜 相转化 PES、SPES、F127和有机溶剂DMF 初生态膜浸入凝胶浴(20-60oC)中相转化成膜 玻璃板上使用刮刀将铸膜液刮制成初生态膜 铸膜液在 60oC下搅4h 静置脱泡4h 将干燥的膜再次浸入凝胶浴中48h 室温下自然干燥48h,高分子不可逆收缩 干燥 润湿

  8. 实验方案设计 1、表面荷电化(一定的盐离子截留) 2、PES及SPES(耐酸耐碱抗氧化) 3、表面偏析(抗污染)

  9. Doing 磺化PES的制备 Different Ds , Different membrane characteristics.

  10. Real Results Ds=7.2

  11. Next Plan And Ideal Results 0 6 Day 0.1 M HCl 0.1 M NaOH Stable Rejection of Some Salts(%) Pure Water Flux(L/(m2h)) Pure Water Flux(L/(m2h)) Rejection of Some Salts(%) Stable NaClO Rejection of Some Salts(%) pH 1 3 5 7 9 11 13 Pure Water Flux(L/(m2h)) 0 1 SPES/PES 0 4000ppm 1 13

  12. Characterization SEM Water contact angle 1H NMR FTIR XPS

  13. 谢谢各位老师 请批评指正!
