英文摘要: Abstract(#br)Pervaporation, an economical, energy-saving and eco-friendly membrane process for separating liquid mixtures, has been considered as a promising candidate for the separation of azeotropic mixtures that are difficult to separate using classical processes. In this study, isopropyl alcohol/water azeotropic mixtures were separated by the pervaporation method using poly(vinyl alcohol)-blended-NaY zeolite (PVA-b-NaY) membranes. For this purpose, different yields of PVA/NaY mixtures were prepared and characterized by using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), water contact angle and atomic force microscopy (AFM). The effect of different parameters, such as PVA/NaY yield, membrane thickness, feed solution concentration and temperature, on the...
