The Polyvinyl chloride (PVC) based zirconium molybdophosphate (ZMP) composite membrane was designed through the important die-casting process. The preparation of this cation exchange membrane is being used to enhance the stability and electrochemical properties. The selection of an appropriate ratio of polymer and filler for attaining the membrane of the highest stability and selectivity has been done by comparing various ratios in terms of ion exchange capacity, water uptake, porosity, membrane potential, and chemical and thermal stability. The used inorganic material was synthesized by the sol-gel method of material synthesis, and the synthesized composite membrane has a combination of PVC polymer and ZMP inorganic material in a 25% and 75% ratio, respectively. The membrane was characterized by using various techniques including SEM, TEM, FTIR, TGA, and EDX analysis, which verified the functional groups, material nature, thermal stability, surface structure, porosity, elemental percentage, ion transportation, etc. The synthesized membrane has indicated appropriate ion-exchange capacity, high stability, reproducibility, and selectivity for salts and heavy metal ions. The electrochemical properties have been studied to determine their applicability in different separation processes.
