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 +
The pervaporation separation of water-isopropanol mixtures was carried out using carboxymethylated poly(vinyl alcohol) (CMPVA) composite membranes. Carboxymethylated PVA (CMPVA) was synthesized by reacting PVA with various concentrations of monochloroacetic acid. Substitution efficiency of the CMPVA
## Abstract Chitosan and poly(vinyl alcohol) blend fibers were prepared by spinning their solution through a viscoseβtype spinneret at 25Β°C into a coagulating bath containing aqueous NaOH and ethanol. The influence of coagulation solution composition on the spinning performance was discussed, and t
