It set up the development of the world recognized high performance nanofiltration composite membrane of aromatic polyamide , on the basis of reviewing the development , the importance in the membrane separation technology , the classification , the fabrication technique and the current development of the research and the application of the nanofiltration membrane . polysulfone was chosen as the material for making the porous substrate because of its excellent compress - to - denseness resistance , its cheap price and its great availability . by fabricating an ultra thin polyamide functional layer on the polysulfone substrate through interfacial polymerization taking piperazine as the monomer in aqueous phase and trimesoyl chloride as the monomer in organic phase , high performance nanofiltration composite membranes of ultra low pressure and ultra high permeating flux were prepared 選擇耐壓密性能優良，價廉易得的聚砜材料為制備復合膜基膜材料，哌嗪為水相單體，均苯三甲酰氯為有機相單體，通過界面聚合反應在基膜表面形成超薄功能層，制備了超低壓高通量聚哌嗪均苯三甲酰胺聚砜納濾復合膜，以0 . 1 mgso _ 4溶液為測試液，所得高脫鹽平板復合膜( )在0 . 4mpa下，脫鹽率為96 . 1 ，通量達85 . 2l |

The study conducted research on the following four fields : firstly , the characteristics of the interfacial polymerization system of piperazine aqueous solution / trimesoyl hexane solution were systematically investigated . the results show that at a certain molar ratio between the two monomers , piperazine and trimesoyl , at the two phase interface , a dense functional layer of ultra low pressure , high permeating flux and high salt rejection formed by controlling the time of interfacial polymerization , such as the composite membrane ( i ) , the concentration in water phase is 0 . 4 % , and 0 . 1 % in organic phase , and the polymerization time is 1 minute 本文主要進行了四個方面的研究，首先系統分析和研究了哌嗪水溶液均苯三甲酰氯正己烷溶液界面聚合體系特征、界面聚合反應中各影響因素對膜性能的影響等，結果發現，當界面處兩相單體(哌嗪和酰氯)分子摩爾比為某一比值時，通過控制界面聚合時間(有機相處理時間) ，可以形成超低壓高通量高脫鹽的致密功能層，如復合膜( ) ，水相濃度為0 . 4 ，有機相濃度為0 . 1 ，聚合時間1min 。 |

On the contrary , because the molecular weight of piperazine monomer is far below the molecular weight cut - off range of nanofiltration , it can easily permeate the functional layer into the w / o interface to keep reacting with trimesoyl molecules 目前紡制的復合效果較好的聚礬中空纖維基膜通量高于200lm一h一， ，對peg20 ( ) 00的截留率達99 % 。 |
