By blending a rigid polymer, sodium alginate ( SA ) , and a flexible polymer, poly ( vinyl alcohol ) ( PVA ) , SA / PVA blend membranes were prepared for the pervaporation separation of ethanol -water mixtures. The rigid SA membrane showed a serious decline in flux and a increase in separation facto
## Abstract The blend membranes of sodium alginate and poly(vinyl alcohol) have been prepared by physical mixing in different ratios (75, 50, and 25%) of sodium alginate with poly(vinyl alcohol). The membranes were crosslinked with glutaraldehyde and used in the pervaporation separation of water +
