| 摘 要： | 采用表面活性剂十二烷基磺酸钠(SDS)和弱极性试剂异丙醇(IPA)作为聚砜基膜表面改性试剂,观察其对中空纤维反渗透复合膜性能的影响.结果表明:选择不同处理剂在一定浓度和时间下处理基膜,所制备复合膜的膜通量提高明显,截留率基本不变;若处理时间过长或者处理剂浓度过大,则膜通量下降.

| Abstract: | Two kinds of surface-active agents:sodium dodecyl sulfate(SDS)and the weak polar reagent isopropyl alco-hol(IPA)as modification reagents are employed on the polysulfone supported membrane surface,also the ef-fects on the performance of hollow fiber reverse osmosis composite membrane are examined.The results show that the supported membrane treated by a certain of concentration of surface-active agents in suitable treat-time,the flux of the membrane icreases dramatically but the desalination of the membranes... |
