摘要用1，6-己二胺、邻苯二胺或哌嗪分别与三甲氧基氯(TMC)在聚砜载体表面进行界面聚合，制得纳滤复合膜。同时，将两种截留分子量(MWCO)不同的聚砜支撑膜引入实验，以期找到多孔基质对制备的膜性能的影响。通过水过滤实验，比较了新制备的三种纳滤膜的水通量和盐截留率。为了使界面聚合更有效，设计了不同的哌嗪与TMC的反应比。结果表明，与其他两种化学药物相比，哌嗪与TMC的反应效果更好，在实验室条件下，聚哌嗪-纳滤膜的盐截留率可达55%；而聚砜S对盐截留率的影响较小。
Abstract Nanofiltration (NF) composite membrane was prepared by interfacial polymerization of 1,6-hexylenediamime, o-phenylenediamine or piperazine with trimesoyl chloride (TMC) on the surface of polysulfone support, respectively. Meanwhile, two polysulfone support membranes with different molecular weight cut off (MWCO) were introduced into this experiment, hoping to find the influence of porous substrates on the prepared membrane performance. Furthermore, the water flux and salt rejection rate of those three kinds of newly-prepared NF composite membranes were compared by water filtration experiment. In order to make interfacial polymerization much more effective, kinds of reaction ratios between piperazine and TMC were designed. It can be seen from the results that piperazine reacts better with TMC compared to the other two chemical medicines, and the salt rejection rate of poly (piperazine) NF composite membranes can arrive at 55% under the condition of laboratory; however, the effects of polysulfone s...
