Chitosan-Cellulose CTS-CL composite membranes were prepared by cross-linking reaction with 3-methy- lglutaric anhydride 3MGA. The cross-linked membranes with CTS-CL were obtained at different CTS con- tents in variations from 50 to 100 wt%, and these membranes were applied in the dehydration of ethanol-wa- ter mixtures. Especially, it was observed that in the case of a composite membrane containing chitosan 80% CTS-CL-80-20 showed a performance with a separation factor of α = 17.1 and a total permeation flux of J = 326 g-m2h. It was observed that the total permeation flux decreased when the cross-linking increased and the increase in the ethanol content in the feed solution showed an increase in the separation factor. The CTS- CL-80-20 showed excellent performance with good mechanical strength and dehydration performance in the ethanol-water mixture separation.
