The blended membrane PVA-Pectin-Glutaraldehide (GA) for ABE permeation has been studied. Permeation studied using the blended membrane PVA-Pectin in mol ratio (1:1), (1:2) and (1:3) with glutaraldehide as crosslinker at various number of monomer (n) 60 and 120. Optimum Composition of membrane can exhibit the highest flux value of permeation ABE since early until equilibrium. The addition of GA do not increase the flux value, but improve the physical properties of PVA membrane. While the addition of pectin to PVA membrane and then crosslinked by GA can increase the flux value. Based on this research, PVA-Pectin-GA membrane is capable of increasing flux value from 0.64 to 1.04 L/m2.h (acetone), 0.25 to 0.32 L/m2.h (n-butanol) and 0.70 to 0.95 L/m2.h (ethanol) compared with PVA membrane. Comparison of the very high flux values indicate that PVA-Pectin-GA membrane is recommended for ABE permeation. © 2015, Sphinx Knowledge House. All rights reserved.
