| Abstract: | Membranes of
poly (ethylene-co-vinyl acetate)
crosslinked with dicumyl peroxide (DCP) were prepared. The permeation
characteristics in the pervaporation process were examined using
chloroform-acetone mixtures. The DCP modified membranes exhibited chloroform
permselectivity. The sorption characteristics, effects of feed concentration
and crosslinking density on pervaporation were also examined. The separation
was found to be maximum at high concentrations of chloroform in the feed
mixture. The maximum separation and flux were found to be associated with a
moderate amount of crosslinking agent in the membrane. As the crosslinking
density was increased, flux and selectivity were found to decrease. |
