SYNTHESIS AND APPLICATION OF ZEOLITE SUPPORTED ZERO VALENT IRON NANOPARTICLES AS MEMBRANE COMPONENT FOR REMOVAL OF NITRATE
G.R.Allahverdiyeva, A.M.Maharramov, U.A.Hasanova

 

Synthesis and characterization of zeolite supported zero valent iron nanoparticles (ZVI NPs) are reported. ZE-ZVI NPs size, composition, morphology were characterized by Scanning Electron Microscopy, Atomic Force Micrsocopy, Energy Dispersive Spectroscopy. Synthesized nanostructures were used as reducing agents of nitrate. Nitrate removal effiency (at initial concentration 50 mg/ml) was rapidly increased from 34 to 90% for ZE-ZVI NPs at 60–240 min time interval. Also was studied the efficacy  of prepared ZE-ZVI NPs as membrane component with 5 % ZVI NPs mass content for nitrate for solution that made 85% for ZE-ZVI NPs respectively. The results of this study indicate that the application of ZE-ZVI NPs as membrane component is advantageous because it allows to prevent the additional pollution of treated solution caused by unreacted ZVI NPs.
