제목 Blend membranes by using PVA/chitosan and crosslinking with TEOS for pervaporation separation of water- Acetic acid mixtures
초록 The membranes were prepared by the poly (vinyl alcohol)/chitosan blending and crosslinked with tetraethyl ortho silicate is reported. The resulting membrane was characterized by FTIR spectroscopy, swelling studies, X-ray diffraction and contact angle testing, Scanning electron microscopy and was finally applied in the pervaporation separation of water acetic mixture. From the FTIR spectra of membranes it was confirmed that the crosslinking reaction between PVA and TEOS successfully occurred. Membrane swelling studies were done at 400C for different water/AA mixtures, swelling degree values were increased with increased in chitosan addition in to polymer matrix. The membrane was applied for the pervaporation separation of water acetic mixture, it was observed that, the membrane showed increased flux with chitosan addition in comparison to pristine PVA/TEOS membrane and with comparatively decreased in separation factor.
