The impact of fabrication conditions on the chitosan (CS) membrane structure and its pervaporation (PV) performance are studied in this paper. Chitosan homogenous membranes were fabricated by casting a chitosan/acetic acid solution, then heating it at various temperatures and for different periods of post-heating time, followed by chemically cross-linking with H 2 SO 4 . The PV separation...
The pervaporation separation of the MeOH/MTBE mixture was performed with three cellulose acetate membranes under various feed compositions and operation temperatures. The results show that the acetylation degree has great influence on the pervaporation properties because the quantity of hydroxyl groups in the polymer matrix leads to different crystallinty degrees. The different extent of the plasticization...
