Fund Project:

The separation of ethanol/water mixture by pervaporation by crosslinked PVA-MA membrane containing LiCl,NaCl and KCl has been investigated.The flux increased markedly when salt content was less than 6 wt% in the dry membrane,and the separation factor increased when ethanol concentration in feed solution was high.The DSC results showed that the membranes adsorbed 5%~8wt% of free water from ethanol/water mixture (50/50wt/wt),which is hardly observed by weighing method.
