【摘要】 以聚砜(PSF)中空纤维超滤膜为基膜,间苯二氨(mPD)为水相单体,均苯三甲酰氯(TMC)为有机相单体,通过界面聚合的方法制备了聚酰胺/聚砜中空纤维复合膜.实验研究了mPD、TMC浓度等工艺条件对膜的截留性能的影响;研究了中空纤维复合膜表面和截面的形貌.所制备的中空纤维复合膜对无机盐具有良好的截留性能,可应用于饮用水制备、纺织废水处理、垃圾渗滤液处理和离子液体的回收等领域.更多还原

【Abstract】 Polyamide/polysulfone hollow fiber composite membranes were prepared by interfacial polymerization of m-phenylenediamine(mPD) aqueous and trimesoyl chloride(TMC) on the inside surface of polysulfone (PSF) hollow fiber ultrafiltration membranes.The prepared conditions were studied such as mPD concentration and TMC concentration.The structures of both inside and section surface of hollow fiber composite membranes were observed by scanning electron microscopy(SEM).The prepared hollow fiber composite membranes have a selective separation to inorganic salts and.can be applied to water production, treatment of pulping wastewater,landfill leachates,and concentration of ionic liquid.更多还原
