Abstract
In this study, cellulose acetate (CA) / nylon66 (NYL66) (95/5) blend membranes with different thicknesses were prepared by a solvent evaporation method. The effects of membrane thickness (almost 7-25μm), feed concentration (70- 95 wt.% isopropanol), and feed temperature (30-60 oC) were investigated on the performance of membrane in the separation of isopropanol-water mixtures. With regard to the results of sorption experiments, it was found that the increase of feed temperature enhanced the overall sorption while by increasing feed concentration, the overall sorption passed through a maximum value at 70 wt. % isopropanol (IPA) . The best separation factor 3080.51 was gained at high isopropanol concentration 95 wt.%, low feed temperature 30 oC, and high membrane thickness 24.62 μm. Regarding the pervaporation separation index, the obtained results showed that proper values for the thickness of membrane, feed temperature, and isopropanol concentration in feed were 24.62 μm, 40 oC, and 70 wt.%, respectively.
