摘要

以导电态纳米聚苯胺(PANI)为添加剂

哌嗪和均苯三甲酰氯(TMC)为反应单体

通过界面聚合反应在聚砜超滤膜上形成复合层制备纳滤膜。采用扫描电子显微镜(SEM)和原子力显微镜(AFM)等对复合膜的性能和结构分别进行了测试和表征。SEM照片证实PANI含量低时

可以在复合膜上分布得比较均匀;AFM图像看出膜表面粗糙度的增加;膜性能的测试结果证实了添加PANI的复合膜水通量得到了提高

同时脱盐率也有变化。最优实验条件下

膜对Na2SO4、MgSO4、MgCl2和NaCl的截留率分别为99.4%、98.5%、85.4%和59.2%。试验结果表明

加入PANI能够提高膜的水通量

并提升了膜的脱盐性能。

Abstract

A composite nanofiltration (NF) membrane was prepared using polyaniline nanoparticles (PANI) as additive by interfacial polymerization between piperazine and trimesoyl chloride (TMC) on the PSF ultrafiltration membrane. The properties and structure of the membrane were characterized with permeation experiment

scanning electron microscopy (SEM) and atomic force microscope (AFM). SEM images showed that PANI was well dispersed in the thin film layer at a low content of PANI. AFM photographs showed the surface of the membrane was rougher than before. NF performance results verified that the flux of the composite membrane was from 45 to 70 L·m-2·h-1

whereas separation performance was improved. Under optimized conditions

the prepared modified composite NF membrane showed that its retentions of Na2SO4

MgSO4

MgCl2 and NaCl were 99.4%

98.5%

85.4% and 59.2%

respectively．Water permeation and separation performance of this NF membrane were improved after addition of PANI into composite membrane.
