The present study investigated the pervaporation performance of novel hydroxypropylated chitosan (HPCS) membranes to separate water from an aqueous alcohol solution. Hydroxypropylated chitosan was prepared from the reaction of chitosan and propylene oxide. The results show that the separation factor

A novel natural polymer blend membrane, namely chitosan/silk fibroin blend membrane, was prepared. The selective solubility and the pervaporation properties of alcohol-water mixture were studied. The results showed that the membrane was water selective and the separation factor of ethanol-water mixt
The structure and the adsorption-desorption properties of zeolite silicalite-I by different treatments after synthesis were studied. The pervaporation properties of the alcohol-water mixture through silicone rubber filled with zeolite silicalite-I by different treatments were also investigated. Trea
## SYNOPSIS A membrane was designed for the separation of a water-alcohol mixture by pervaporation on the basis of the difference in hydrogen-bonding interaction between two components of the membrane. Two kinds of poly (vinyl alcohol) -g-maleic anhydride/methyl methacrylate membrane were prepared
