Separation of Aqueous Isopropanol Through Chitosan/Poly (Vinyl Alcohol) Blended Membranes by Pervaporation

International Islamic University Malaysia Engineering Journal, 2012
Blend membranes consisting of chitosan/poly (vinyl alcohol) (CS/PVA) were prepared from a solution casting method and characterized via the pervaporation separation of isopropanol-water mixtures.  The solution of pure chitosan was blended with poly(vinyl
