| Popis: | Polyvinyl chloride (PVC) based Tin-Tungusto-Arsenate (TTA) composite membrane was designed through the important die casting process. The used inorganic material was synthesized by sol-gel method of material synthesis. The synthesized composite membrane has the combination of PVC polymer and TTA inorganic material that shows novel and better chemical plus mechanical stabilities. The synthesized membrane is differentiated and characterized by their chemical composition, ion exchange capacity, x-ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy, thermo gravimetric (TGA), differential thermal (DTA) analysis and scanning electron microscopy (SEM). These characterizations verified the functional groups, material nature, thermal stability, surface structure, porosity, elemental percentage, ion transportation etc. Membrane shows good ion-exchange capacity, high stability, reproducibility and selectivity for salts and heavy metal ions. To observe the electrochemical studies of membrane KCl, NaCl and LiCl electrolyte solutions are experimentally analyzed and the obtaining data has been theoretically applied. The charge density of membrane shows KCl > NaCl > LiCl order whereas observed potential, transport number and mobility ratio follows KCl |
