| 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. |
