摘要： Sulfonated polypropylene membranes loaded with different kinds of counter-ions were prepared by heterogeneous chiorosulfonation reaction of polypropylene membrane followed by hydrolysis and ion-exchange reaction. The membranes obtained were used for selective separation of ethanol/water mixtures by pervaporation. The effects of counter-ion species, ion-exchange capacity, solution composition, thickness of membrane and temperature on the separation behavior of the membranes were investigated. Microstructure and morphology of the membranes were examined by X-ray and SEMas well.
