| Abstract: | The effect of additives CaCl\-2 and CaCl\-2/H\-2O on the properties of polyacrylonitrile(PAN) ultrafiltration(UF) membranes prepared by phase inversion process was studied. The dissolving capacity of the casting solution for CaCl\-2 was enhanced by the addition of H\-2O. The membranes are characterized in terms of the pure water flux and molecular weight cut\|off(MWCO). The addition of CaCl\-2 or CaCl\-2/H\-2O to the casting solution increases the resulting membrane permeability. |
