Fabrication, characterization, transportation of ions and antibacterial potential of polystyrene based Cu3 (PO4)2/Ni3 (PO4)2 composite membrane

Novel organic–inorganic composite membrane was successfully prepared by sol–gel process. Such composite membrane shows best thermal, mechanical and chemical stability as well as good ion exchange property. Structural configuration of membrane was confirmed by TEM, XRD and FTIR analysis while thermal properties examined by TGA/DTA and LCR analysis. Teorell, Meyer Siever, method was used to determine the theoretical values of potential. The observed potentials and charge densities seems to follow KCl < NaCl < LiCl and LiCl < NaCl < KCl order respectively. By potential observation transport number, mobility ratio, distribution coefficient, charge effectiveness and fixed charge density of ions were calculated very easily.
