| Abstract: | PVA/PAN pervaporation composite membranes with active layer thickness of 1 to 10 |ìm were prepared and were for the separation of ethanol water mixture. Experiment results show that heat treatment conditions have remarkable effects on the permselectivity, permeability and pervaporation separation index. The optimum heat treatment condition was achieved. |
