Abstract

The important die casting process was used to create the polyvinyl chloride (PVC) based zirconium molybdophosphate (ZMP) composite membrane. This cation exchange membrane is being prepared to improve its stability and electrochemical properties. The optimum polymer/filler ratio for achieving the maximum stability and selectivity was determined by evaluating several ratios in terms of ion exchange capacity, water absorption, porosity, membrane potential, and chemical and thermal stability. The employed inorganic material was synthesised using the sol-gel method of material synthesis, and the synthesised composite membrane has a 25% and 75% ratio of PVC polymer and ZMP inorganic material, respectively. Various techniques were used to characterise the membrane, including SEM, TEM, FTIR, TGA, and EDX analysis, which confirmed the functional groups, material nature, thermal stability, surface structure, porosity, elemental percentage, ion transportation, and so on. The fabricated membrane demonstrated adequate ion-exchange capacity, good stability, repeatability, and selectivity for salts and heavy metal ions. The electrochemical properties were investigated in order to establish their usefulness in various separation techniques.
