Mixed matrix polyvinyl chloride-copper ferrite nanoparticles cation exchange membranes were prepared by casting solution technique. The effect of CuFe 2 O 4 nanoparticles concentration on electrochemical properties of prepared membranes was investigated. The CuFe 2 O 4 nanoparticles were synthesized by chemical precipitation technique. The formation of copper ferrite nanoparticles was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD). Scanning microscopy images showed uniform distribution of particles in the membrane matrix. Membrane surface hydrophilicity and charge density, membranes potential, transport number (> 97%) and permselectivity (> 96%) were enhanced by using CuFe 2 O 4 nanoparticles in the membrane body. Also, ion exchange capacity and cation flux were increased initially by utilizing CuFe 2 O 4 nanoparticles up to 1 wt% in the casting solution and then followed by a decreasing trend by adding more concentration up to 8 wt%. The PVC-CuFe 2 O 4 membranes displayed lower electrical resistance (< 4 Ω.Cm 2 ) compared to unmodified ones.
