【摘要】：以聚砜(PSF)中空纖維超濾膜為基膜,2,2-二(1-羥基-1-三氟甲基-2,2,2-三氟乙基)-4,4-亞甲基雙苯胺(BHTTM)為水相單體,均苯三甲酰氯(TMC)為有機(jī)相單體,采用界面聚合方法制備了中空纖維復(fù)合納濾膜,分析了基膜和納濾膜的微觀結(jié)構(gòu)、表面粗糙度、紅外光譜和親水性,討論了不同反應(yīng)時(shí)間、熱處理時(shí)間、單體濃度等制備條件對(duì)納濾膜性能的影響.結(jié)果表明,當(dāng)水相1%(w/v)BHTTM、油相0.15%(w/v)TMC和界面聚合時(shí)間10s,并在60℃下熱處理10 min時(shí),所得納濾膜具有良好的分離性能,對(duì)于無機(jī)鹽的截留率大小順序均為Na_2SO_4MgSO_4NaClMgCl_2,納濾膜表面帶負(fù)電.
[Abstract]:The polysulfone (PSF) hollow fiber ultrafiltration membrane was used as the base membrane. The hollow fiber composite nanofiltration membrane was prepared by interfacial polymerization of 4-methylenedianiline (BHTTMT) as aqueous monomer and benzoyl chloride (TMC) as organic monomer. The microstructure, surface roughness, infrared spectrum and hydrophilicity of substrate and nanofiltration membranes were analyzed. The effects of different reaction time, heat treatment time and monomer concentration on the properties of nanofiltration membranes were discussed. When the water phase 1 / w / v / t BHTTM, the oil phase 0.15 and the interfacial polymerization time 10s, and heat treated at 60 鈩，
