Pervaporation is one of the most active research areas in membrane science. It is an important component for chemical separations and has attached great attentions. In this paper

based on three main mixture systems viz.

dehydration of organic solvents

separation of organics form aqueous solution

separation of organicorganic mixtures

the recent development in pervaporation is reviewed

respectively. Separation of organic-organic mixtures by pervaporation is discussed with emphasis on the following aspects: polar/non-polar mixtures

aromatic/ aliphatic mixtures

aromatic/alicyclic mixtures

isomers

multi-mixtures and desulfurization of gasoline. Finally

the advancement of further research and development about pervaporation are prospected.
