“…It also indicated that real part of impedance also shows frequency dependent behavior at very low frequency and the value of Z΄=Zcosθ have increases quickly but at high frequency it shows frequency independent characteristics, means that it shows constant nature which has calculated by the given formula. The graph of imaginary part of impedance that is Z˝=Zsinθ also shows the frequency dependent behavior, but it increases quickly at zero frequency or slightly more than but again at high frequency it behaves as constant property [33]. The antibacterial observation which was carried out to investigate the bacterial action of membrane material shows in Table1.…”

The copper phosphate {Co 3 (PO 4 ) 2 } inorganic material has been synthesized by the sol gel method. The PVC supported CP membrane was designed by the mixing of inorganic CP and organic polyvinyl chloride (PVC) materials in 1:3 ratios of percentage. This membrane is used as a barrier for transportation of electrolyte and heavy metal ions due the charged particles on it. Due to this nature of membrane, it governs to adsorb as well as absorb characteristics of cations and anions. The structural, thermal and electrochemical characterizations were done by using different sophisticated techniques like FTIR, XRD, TGA/DTA as well as SEM-EDX, LCR and potentiometer analysis. The characterizations of material and membrane indicated the information of functional groups, material nature, thermal stability, surface structure, porosity, elemental percentages, dielectric nature, ionic transportation etc. Teorell-Meyer-Sievers (TMS) theoretical method is used to determine the charge density of membrane which is an important theory is used to analyze the performance of membrane. The other important parameters of membrane have also been determined easily by the help of obtained values of charge densities.

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

“…For this purpose, a variety of ion exchange membranes such as organic, inorganic and composite membranes have been used [11–16]. However, inorganic material plasticizes in an organic polymer such as polyvinyl chloride (PVC) in the form of the composite are very stable at high temperature as well as in acidic and basic media [17–20]. PVC is stable in all acid /base and all inorganic chemicals [21].…”

In the present study, a polyvinyl chloride-based barium tungstate ion-exchange membrane was synthesized by sol–gel method. The structure of membrane was studied in terms of Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. X-ray diffraction analysis confirms crystalline form of the composite membrane without any other impurity. Scanning electron microscopy and Fourier transform infrared spectroscopy analysis show the uniform arrangement of particles in the membrane with crack-free surface structure and presence of different functional groups of the organic-inorganic materials. The electrochemical properties like surface charge density ( D), transport number and mobility ratio of the ion-exchange composite membrane were theoretically evaluated and compared with observed values using “Teorell, Meyers and Sievers” method. Transport number follows the order as KCl <NaCl < LiCl < NH4Cl, while the surface charge density showed reversed order. The results showed that the low concentration of electrolytes favors the high mobility of univalent cation in the present study. The above result proves the analytical utility of polyvinyl chloride-based barium tungstate ion-exchange membrane in environmental management.
