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 material . At present

poly (dimethyl siloxane) (PDMS) is the most widely applied membrane material in organophilic pervaporation .Progress inmodifation of the organic permselective PDMS pervaporative membrane was reviewed in this paper .And its development and prospect were described .
