Synthesis, structural characterization, electrochemical, and electrical study of polystyrene-based manganous tungstate composite cation exchange membrane

The polystyrene-based manganous tungstate composite membrane was prepared by applying sol-gel method. The membrane was characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, differential thermal analysis, scanning electron microscopy, and (LCR) study. Membrane was found to be crystalline, the arrangement of particle was uniform, and there were no sign of visible breakage or cracks. The theoretical value of potential was determined by Teorell-Meyer-Sievers, method and the electrochemical property was measured by a potentiometer. From observation, it is clear that the membrane potential increases with decreasing the concentration of electrolytes and the charge density follows the reverse order of potentials. By observing transport number the mobility ratio, distribution coefficient, and charge effectiveness can be calculated very easily.
