چکیده مقاله:

In this research, thin film heterogeneous cation exchange membrane was prepared by interfacialpolymerization of polyacrylic acid-co-iron nickel oxide nanoparticles on PVC based substrate. Spectraanalysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layercovers the membranes by simple gel network entanglement. Results exhibited that membrane watercontent was decreased by graft polymerization of PAA/Fe2NiO4 nanoparticles on membrane surface.Membrane potential, transport number and permselectivity all were declined initially by PAAinterfacial polymerization in NaCl ionic solution and then began to increase. The membrane transportnumber and permselectivity showed decreasing trend in bivalent (BaCl2) ionic solution. The sodiumflux and permeability were improved sharply by PAA graft polymerization on membrane surface andthen decreased slightly by graft polymerization of PAA/Fe2NiO4 nanoparticles. Different behavior wasfound for barium flux and permeability. Membrane areal electrical resistance was also decreased byintroducing interfacial graft polymerization on membrane surface.
