Separation of water-azeotropes using pervaporation technique through polymers blend membrane |
| 초록 |
In this study attempt was made to prepared the membranes from blending of hydrophilic polymers namely poly (vinyl alcohol) (PVA) and poly (vinyl amine) (PVAm).And stabilized it in the water using the chemical crosslinking using the glutardehyde as crosslinking agent for dehydration of water-azeotropes. The characterization of membranes were done by using FTIR, XRD, DSC, SEM and swelling study. MB1.5 membrane was the best one in all since it exhibited higher separation index. By using blend membrane (MB1.5), the flux through a 65-m film increased from 0.01 to 0.47 kg/m2h at an acetonitrile/water feed ratio between 20/80 and 5/95 w/w at 30 C while separation factor increased from the 5055 to 100.84 attributed to the higher hydrophilicity of blend membranes. It was observed from the obtained pervaporation data, membrane showed higher separation ability for water-isopropanol mixture in comparison to water-acetonitrile.. |
