The polyvinyl chloride (PVC) based carboxymethyl cellulose Ce(IV) molybdophosphate composite membrane are prepared and characterized by the Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Fourier transformed infrared (FTIR), and thermogravimetric analysis (TGA) studies. The inorganic–organic composite membrane was found to be crystalline in nature with consistent arrangement of particles and indicating no sign of visible cracks. The FTIR spectra verify the binding of organic polymer with inorganic component. The membrane was found to be cation-selective. The order of surface charge density for uni-univalent electrolytes solution was found to be KCl > NaCl > LiCl.

The polystyrene based barium phosphate composite membrane was prepared by co-precipitation method. The composite membrane has been characterized on the basis of scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transformed infrared (FTIR) and thermo gravimetric analysis (TGA) and differential scanning calorimetry (DSC) studies. Ion-exchange capacity, water uptake, porosity,thickness and stability studies were also carried out to determine the preliminary ion-exchange properties of the composite membrane. The order of transport number of cation for univalent electrolytes solution was found to be KCl < NaCl < LiCl. The antibacterial activity of composite membrane was investigated against some bacteria.

The polyvinyl chloride (PVC) based polyvinyl alcohol Sn(IV) tungstate composite membrane was prepared by solution casting method. The sample was characterized by the Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Fourier transformed infrared (FTIR) and Thermo gravimetric analysis (TGA) studies. The membrane potential of composite membrane for various univalent electrolyte was found to follow the increasing order KCl < NaCl < LiCl. The order of surface charge density for univalent electrolytes solution was found to be LiCl < NaCl < KCl.

The polyvinyl chloride (PVC) based polyvinyl alcohol zinc oxide composite membrane was successfully prepared by solution casting technique. Membrane properties were studied in terms of water uptake,porosity, thickness, ion-exchange capacity and swelling. The physico-chemical characterization of the material was studied using Fourier transform infrared (FTIR) spectroscopy, thermogravimetry analysis (TGA), X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies. The important application of this composite ion-exchange membrane is in environmental separation of heavy metal ions transport. The increasing order of transport number of cation as HgCl2 < PbCl2 < CdCl2.
