STA-PVAm polyelectrolyte complex surface deposited PVA membrane for dehydration of Epichlorohydrin, isopropanol, and water ternary feed mixtures |
| 초록 |
In this study Poly (vinyl alcohol) (PVA)-tetraethyl orthosilicate organic–inorganic hybrid membrane has prepared and modified the membrane surface by layer-by-layer deposition of a PVAm/silicotungstic acid polyelectrolyte for the pervaporation dehydration of ECH/IPA/water mixtures. Membrane characterization using FTIR, FE-SEM, and SEM-EDS, XPS and TGA measurements was carried out. In pervaporation experiments at 30 °C, the flux decreased 0.14 to 0.05 kg m-2 h-1 and separation factor increased from and 2099 to 13320 with TEOS addition in the PVA membrane was observed. And for the layer by layer deposition on PVA-TEOS (4) membranes flux increased and separation factor decreased from 0.14 to 0.28 kg m-2 h and 2099 to 416 with the number of layer of deposition were observed. The pervaporation output of the PVA-TEOS and layer by layer PVA-TEOS membranes reflects the both membranes have excellent ability in epichlorohydrin, isopropanol and water ternary mixture pervaporation dehydration. |
