Abstract: After cross-linked by using Cr2(SO4)3, gelatin membrane was used successfully for separation of ethanol/water mixture by pervaporation.And the effects of time, downstream pressure, temparature, and feed concentration on flux and separation coefficient were studied.

Key words: Gelatin membrane, Pervaporation, Separation of ethanol/water
