以间苯二胺和均苯三甲酰氯为原料，通过界面聚合法制备了截留分子量达360 Da的聚砜基中空纤维。中空纤维，其特征在于在扫描电子显微镜和原子力显微镜，渗透性，截留分子量（MWCO），孔径分布和表面zeta电位。TMC浓度的增加降低了膜的MWCO和平均孔径。随着TMC浓度从0.1增加到1重量%，MWCO从780降低到360 Da，平均孔半径从7.3减小到5 μ m。用该中空纤维成功地处理了含四种活性染料和无机盐的印染废水。一个完全预测的稳态多组分模型的开发，以量化系统的性能。
Polysulfone based nanofiltration (NF) hollow fibers upto 360 Da cut off were prepared by interfacial polymerization of meta-phenylenediamine and trimesoyl chloride. Hollow fibers were characterized in terms of scanning electron and atomic force microscopy, permeability, molecular weight cut off (MWCO), pore size distribution and surface zeta potential. Increase in TMC concentration reduced the MWCO and average pore size of the membrane. MWCO was decreased from 780 to 360 Da and average pore radius was reduced from 7.3 to 5 Å as TMC concentration increased from 0.1 to 1 wt%. A textile effluent containing four reactive dyes and salt was successfully treated by this hollow fiber. A completely predictive steady state multicomponent model was developed to quantify the system performance.
