Electrochemical Study and Mathematical modelling of PVC embedded TTP Composite membrane using TMS theory

Abstract

The membrane potential has been studied to characterize the ion-transport processes across a charged membrane while utilizing electrolytes to synthesized PVC embedded Tin tungstophosphate (TTP) composite membranes (KCl, NaCl KNO3 and NaNO3). It is discovered that the membrane was found to be cation-selective and that the electrolytes gave membrane potential in the following order: NaCl>KCl>NaNO3>KNO3. The estimates of the electrolytes of this membrane's fixed-charge density, charge effectiveness, and transport characteristics were made using the results. The most significant factor controlling transport phenomena in membranes is the fixed-charge density. It is calculated using the TMS approach; because of the potential adsorption of particular ions, it depends on the composition of the feed. The ionic radii of the counter-ions affect the electrolytes' ability to conduct charges in a membrane in a certain sequence. The theoretical prediction for membrane potential is remarkably compatible with the experimental findings. SEM, EDX, XRD and FTIR are used to examine the morphology of the membrane surface, and TG/DTA are used to evaluate thermal stability.
