摘要：

Blend membrane consisting of poly(vinyl alcohol)(PVA) and chitosan was prepared from solvent casting technique for effective separation of ethanol-water mixture by pervaporation. Selectivity toward water and the flux through the blend membrane, crosslinked with glutaraldehyde at the concention of 4 x 10(-6) mol/g, were approximately 450 and 0.47 kg/m2.hr, respectively.
