Abstract

Pervaporation hydrophilic membranes were prepared by blending acrylic acid acrylamide copolymer with PVA and used to separate 40% ~ 95% (mass%) ethanol water solution. The effect of the membrane heated temperature, separation temperature, mol ratio of AA and AM as well as pH value of the membrane made solution on the property of membrane were studied. On condition that AA∶AM=1∶1(mol), copolymer∶PVA=1∶1(mass), pH value of the membrane made solution was 7, the membrane heated temperature was 160 ℃ and 95% ethanol water solution was separated at 50 ℃, separation factor and total flux of the membrane respectively reached 1.3 and 8 times of that of PVA membrane.
