The synthetic organic-inorganic composite membranes have enormous applications in the field of filtration and purification processes. The newly synthesized PVC (polyvinyl chloride) incorporated ZP (zinc phosphate) composite membrane is used as a barrier for the transportation of some strong electrolyte solutions like KCl, NaCl and LiCl. The composite material which used to make the membrane was qualitatively synthesized by sol-gel method of material synthesis. To characterize the structural and thermal properties of membrane there are different techniques like FTIR, XRD, TGA/DTA, SEM-EDX, LCR have been used. By characterizations it is clear that the material has crystalline nature, thermally stable and no breakages or cracks are found on membrane the surface. The electrochemical observation was done by potentiometer, which shows that the membrane is cation selective. To determine the charge density of membrane Teorell-Meyer-Sievers method is used. The observed potential and charge density of the incubated membrane follows KCl<NaCl<LiCl and KCl>NaCl>LiCl order respectively. The other important parameters like transport number, mobility ratio, charge effectiveness are also calculated by observed potential values.

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.

In the research, composite membrane derived from Acrylonitrile butadiene styrene (ABS), Polyvinyl chloride (PVC) were prepared with 30wt.%. In next step, adding 0.125, 0.250, 0.50wt.% of nanocomposite (CAU-10-H) in Acrylonitrile butadiene styrene (ABS), Polyvinyl chloride (PVC) was obtained. All of the polymeric and nanocomposite membranes were e fabricated by the solvent foundry method use a dimethylacetamide solvent. The performance of prepared membranes was calculated for methane and ethane at the feed pressure of 2.5, 3.0, and 3.5 bar at a temperature of 35°C. Results showed that in most cases, increasing the percentage of Acrylonitrile butadiene styrene (ABS), Polyvinyl chloride (PVC). the permeability of CH4 and C2H6 increased.
