Abstract:
 Using polysulfone (PSF) hollow fiber membrane as the supporting membrane,  fluoropolyamide /polysulfone (PSF) hollow fiber thin film composite (TFC)  nanofiltration (NF) membranes were prepared by the interfacial polymerization of 2,2’-bis(1-hydroxyl-1-trifluoromethyl-2,2,2-trifluoroethyl)-4,4’-methylenedianiline (BHTTM) and trimesoyl chloride (TMC). The morphology and surface properties of hollow fiber TFC NF membranes were characterized by scanning electron microscope (SEM), atomic force microscopy (AFM), attenuated total reflectance infrared (ATR-IR) and contact angle instrument. The experimental results showed that the hollow fiber TFC NF membrane prepared under the following condition gained the best performance: 1.0 % (w/v) BHTTM and 0.15% (w/v) TMC for 10s reaction and 10min heat treatment in 60℃. The rejections of the resulting NF membrane for different inorganic electrolyte solutions decreased in the following order: Na2SO4, MgSO4, NaCl, MgCl2, which was typical characteristics of negatively charged NF membranes.
