Fund Project:

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.
