“…The potential observation of ions is a simple and influential method which is used to determine the transport property of ions across the charged membrane. The transport phenomenon of electrolyte ions through membrane system is very important process for the industrial application point of views [10][11][12]. The bi-ionic potential (BIP) is defined as a potential difference arising between the solutions of different electrolyte with same molar concentrations at a constant temperature and pressure when they are separated by a uniform charged membrane [13][14][15].…”

Parchment impregnated Ba(II) molybdate artificial membrane was prepared by the ion-interaction method using BaCl2 and Na2MoO4 solutions. The prepared membrane was characterized by sophisticated instrumental techniques such as Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier-transform infrared (FT-IR) spectroscopy, Thermogravimetric analysis (TGA)/Differential thermal analysis (DTA), X-ray diffraction (XRD) and Energy dispersive X-ray (EDX) analysis. The artificial membrane was tested for its antimicrobial activity against Gram-negative (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus) microorganism. The effective fixed charge density of the prepared membrane has been used individually to calculate theoretical bi-ionic potentials (BIP) and compared with experimentally determined values of bi-ionic potential. The selectivity of ions for the membrane has been found as K+>Na+>Li+ which on the basis of the Eisenman-Sherry model of membrane selectivity, points towards the low field strength of the charge groups joined to the membrane matrix. Membrane conductance values has also been experimentally determined.Â Â
