Synthesis, characterization, and electrochemical observation of PVC-supported strontium tungstate inorganic precipitated composite membrane

PVC-supported strontium tungstate composite membrane was prepared by the cast die frame of membrane preparation. The strontium tungstate material was qualitatively synthesized by sol-gel method of material synthesis. The membrane was characterized by SEM, XRD, FTIR, and simultaneous TGA/DTA studies. These characterizations demonstrated the material nature, functional groups, surface texture, porosity, thermal stability, ion-exchange property etc. The electrochemical properties have been studied by TMS theoretical approach which easily determines the important parameters of membranes like transport number, mobility ratio, charge density, charge effectiveness etc. The theoretical and observed electrolyte potential calculations get the values of charge density. The observed ionic potential and graphical fixed-charge density of both the membranes follows CaCl2 MgCl2 > BeCl2 order, respectively.
