摘要
采用间苯二胺(MPD)和均苯三甲酰氯(TMC)分别为水油相,通过界面聚合反应,加入纳米聚苯胺(PANI),得到改性的反渗透复合膜。复合膜结构的表征采用扫描电子显微镜(SEM)和原子力显微镜(AFM)。同时对复合膜的耐-氯性能进行评估。结果表明,改性后复合膜的通量提高,同时脱盐率也有一定提升,在PANI含量为0.1 g/L时,截留性能最佳。在保持良好的分离性能的同时随着PANI含量的提升,复合膜的耐氯性也得到很大的改善。
A modified reverse osmosis composite membrane was prepared via interfacial polymerization with M-phenylenediamine（MPD） and trimesoyl chloride（TMC） was used as aqueous and oil phase respectively, and polyaniline nanoparticles（PAN1） was added to modified the composite membraneThe structure of the composite membrane was .characterized by scanning electron microscopy （SEM） and atomic force microscopy （AFM）, meanwhile the chlorine resistant properties of membrane were evaluated.The results showed that the water flux increased and also the rejection rate improved after the composite membrane modification. When PANI content was 0.1 g/L, the rejection rate was the best. With the increasing of PANI content, the chlorine resistance of composite membrane hadbeen greatly improved while maintaining the good separation performance.
