title: Effect of additive on the formation of polyacrylonitrile membrane.
abstract: The effect of additives CaCl2 and CaCl2/H2O on the properties of polyacrylonitrile (PAN) ultrafiltration (UF) membranes prepared by phase inversion process was studied. The dissolving capacity of the casting solution for CaCl2 was enhanced by the addition of H2O. The membranes are characterized in terms of the pure water flux and molecular weight cut-off (MWCO). The addition of CaCl2 or CaCl2/H2O to the casting solution increases the resulting membrane permeability.
