عنوان انگلیسی Thin Film Heterogeneous Ion Exchange Membranes Prepared by Interfacial Polymerization of PAA-co-Iron-Nickel Oxide Nanoparticles on Polyvinylchloride Based Substrate
چکیده انگلیسی مقاله In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content was decreased by using of PAA/Fe2NiO4 nanoparticles interfacial polymerization. Membrane potential, transport number and permselectivity all were declined initially by PAA interfacial polymerization in NaCl ionic solution and then began to increase. The membrane transport number and permselectivity showed decreasing trend in bivalent (BaCl2) ionic solution. The sodium flux and permeability were improved sharply by PAA graft polymerization on membrane surface and then decreased slightly by using of Fe2NiO4 nanoparticles in surface modifier. Different trend was found for barium flux and permeability. Membrane areal electrical resistance was also decreased by introducing interfacial graft polymerization on membrane surface.
