Blend membranes prepared from poly(vinyl alcohol) (PVA) and chitosan (CS) were crosslinked with glutaraldehyde and used in the pervaporation dehydration of 1,4-dioxane. Membranes were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scan

## Abstract Crosslinked chitosan membranes were synthesized using glutaraldehyde and characterized by infraβred (IR) and wideβangle Xβray diffraction (WAXD) spectroscopic methods. The membranes were applied for the pervaporationβbased dehydration of the highly hazardous and hypergolic unsymmetrical
## Abstract Blend membranes of poly(vinyl alcohol) (PVA) and sodium alginate (NaAlg) were prepared by solution casting and crosslinked with glutaraldehyde (GA). Polymer blend compatibility was studied in water by measuring solution viscosity at 30Β°C. From the viscosity data, interaction parameters
