Acetic acid dehydration by pervaporation

In this study polyvinyl alcohol (PVA) was modified with two different agents - glutaraldehyde and formaldehyde - by a method called crosslinking and the membranes produced were used to separate mixtures of acetic acid and water. The effect of type of crosslinking agent, feed composition and feed temperature on the pervaporation characteristics were investigated. (C) 2001 Elsevier Science B.V. All rights reserved.
