The pervaporation separation and the swelling behavior of acetic acid-water mixtures were investigated at 30, 40, and 50ΠC using the crosslinked poly(vinyl alcohol) (PVA) membranes with varying the poly(acrylic acid) (PAA) contents and the acetic acid concentration in the feed mixture. Typically, fo
## Abstract Novel pervaporation (PV) membranes for ethanol dehydration were prepared by blend poly(vinyl alcohol) (PVA) and carboxymethyl chitosan (CMCS), followed by the crosslinking reaction with glutaraldehyde; the structure and miscibility of the blend membranes were characterized by Fourier tr
For the purposes of the water-selective membrane material development for pervaporation separation, poly (vinyl alcohol) (PVA) was crosslinked with a low molecular weight of poly (acrylic acid) ( PAA) . The crosslinking reactions between PVA and PAA were characterized through IR spectroscopy, differ
