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 .
