| 摘 要： | 有机物优先透过的渗透汽化过程(Organophilic Pervaporation,O-PV)是一种膜分离技术,可以有效脱除化学、制药、电子、石化、印刷、涂料、纺织等工业废水中含有的微量挥发性有机物(Volatile organic compounds,VOCs),如苯、甲苯、三氯乙烯、氯仿和苯酚等.膜(一般指高分子膜)是O-PV过程的核心,而用于O-PV的膜分离性能主要取决于膜材料所具有的内在分离性能.聚二甲基硅氧烷(Poly(dimethyl siloxane), PDMS )是目前为止应用最为广泛的O-PV膜材料.本文综述了有机物优先透过的PDMS渗透汽化膜的改性研究进展,并展望了其未来的发展方向和前景.

| Abstract: | Volatile organic compounds(VOCs),e.g.,benzene,toluene,trichloroethylene,chloroform and phenol,in several industrial wastewaters,e.g.,chemistry,pharmacy,eclectron,petroleum,printing,dope and textile,can be effectively removed by a membrane separation techonology named as organophilic pervaporation.Membrane is the core part of an organophilic pervaporation process.And the separation properties of a given membrane used for organophilic pervaporation depend on the inherent separating properties of the membrane ... |
