Pervaporation of Ethyl Acetate-Water Mixture through Sago/PVA Blend Membranes Cross-linked with Glutaraldehyde

摘要

Sago composite membrane possesses a microporous polysulfone substrate were prepared and tested for dehydration of ethyl acetate/water mixture. Sago composite membrane has been cross-linked successfully by glutaraldehyde. The membranes were characterized by Degree of swelling (DS) and scanning electron micrographs (SEM). Pervaporation of ethyl acetate - water mixture was conducted over a range of water concentration (1-4wt%) in feed solution at varied temperature from 30°C to 60°C.
