Separation Performance of Sodium Alginate / Poly ( Vinyl Pyrrolidone ) Membranes for Aqueous / Dimethylformamide Mixtures by Vapor Permeation and Vapor Permeation with Temperature Difference Methods


In this study sodium alginate (NaAlg)/poly(vinyl pyrrolidone) (PVP) blend membranes were prepared and crosslinked with CaCl2 (0.1 Molarity (M)) for the separation of aqueous/dimethylformamide (DMF) mixtures. Membranes were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and their performance was examined… (More)
