Abstract
Poly(vinyl alcohol) (PVA) coating solution containing glutaraldehyde (GA) and maleic anhydride (MA) as crosslinking agents was coated onto hydrolyzed poly acrylonitrile (PAN) hollow fiber membranes. The permselectivities of the resulting composite membranes prepared varying the reaction temperature and the concentration of the crosslinking agents were tested for 90 wt% ethanol aqueous mixtures by the pervaporation technique at $60^{\circ}C$. In general, the flux decreased while the selectivity increased for the increases of the reaction temperature and the crosslinking concentration. In case of GA as a crosslinking, the flux $165g/m^2hr$ and the separation factor 81 were obtained at GA 11 wt% and the reaction temperature $120^{\circ}C$. And for the case of MA, the flux $174g/m^2hr$ and the separation factor 73 were obtained at MA 11 wt% and the reaction temperature $120^{\circ}C$.
