Parchment impregnated PbWO4 artificial membrane was prepared by ion-interaction method. SEM reveals the formation of composite material with uniform surface morphology. The membrane was characterized for its thermal stability by TGA. Crystallinity and phosphorylation of the membrane was confirmed by XRD and FT-IR. The values of bi-ionic potential has been measured with various combinations of bi-univalent electrolytes at different concentrations. Theoretical values of BIP have been calculated using the BIP theories developed recently by Toyoshima et al. and Tasaka et al. based on the principles of non-equilibrium thermodynamics. Comparison of experimental and theoretical BIP values shows that theoretical equations of BIP are applicable to the parchment impregnated membrane. Membrane conductivity in contact with a single electrolyte has been experimentally determined to evaluate the selectivity of the membrane using the predetermined values of intramembrane mobility ratio. The selectivity sequence of the artificial membrane is found to be Zn++>Ca++>Mg++. The prepared membrane can be considered as an excellent material for desalination and wastewater treatment applications.
