| 摘 要： | 本文用 EW=1563的 Nafion 树脂为原料,纺制了内径为0.44mm,外径为1mm 的中空纤维膜,并将其转化成 K 型、Na 型和 H 型。研究了不同类型的 Nafion 中空纤维膜对水的吸附行为,并初步探讨了 Nafion-H 中空纤维膜对极性不同的两种液体的分离效果。结果表明,水在Nafion 中空纤维膜中的扩散系数与膜中阳离子半径有关,阳离子半径愈小,扩散系数愈大;水在Nafion-K 中空膜中的扩散系数随温度的升高而增加,求得的扩散活化能为44KJ/mol;同时还表明,Nafion-H 中空纤维膜对甲苯-乙醇混合溶液透过蒸发的分离效果良好。

| Abstract: | In this paper,a hollow fiber membrane with O.D.1mm and I.D.0.44mm was spunfrom Nafion-F resin with EW 1563 and then was transfered to Nation-K,Na and H hollowfibers.Their behaviors of sorption water and the seperation ability of Nafion-H for mixturesolution made from different polar liquids was also studied.The result shows that diffusionof water in these membrane is depended on the diameter of cation in macromolecule ofmatrix;the smaller the diameter of cation,the larger the diffusion coefficient is.The diffu-sion coefficient of water in Nafion-K increases as the temperature increasing and the diffu-sion activation energy is 44 kJ/mol.The result also shows that Nafion-H hollow fiber israther effective for the separation of toluene-alcohol mixture. |
