Elucidating the stability and electrochemical potential of PVP@ZP+Ze composite membrane with special reference to polymer and ion exchange materials concentration

The chemical, mechanical, and electrochemical stabilities of composite membranes are pivotal to boost their filtering performance and application. This research is centered on the development of a composite membrane, from polyvinylpyrrolidone (25%) supported zirconium phosphate and zeolite (ZP+Ze). The membrane potential was evaluated using KCl, NaCl, NaNO3, and KNO3, electrolyte solutions to characterize the ion-transport phenomena over the charged membrane. The analysis showed that by transporting positive ions,the membrane manifests cation selectivity. For a given electrolyte, the sequence of potential values followed the trend KNO3
