Abstract

Abstract: The sulfonated polyethylene hollow fiber ion-exchange membranes with different ionexchange capacity (IEC) were prepared by heterogeneous photochemical chlorosulfonation reaction. The effects of temperature and IEC on the pervaporation of a near azeotropic isopropanol/water feed mixture were studied.

Key words: pervaporation, hollow fiber membrane, ion-exchange membrane, membrane separation, isopropanol/water mixture, sulfonated polyethylene
