GREEN SYNTHESIS OF IRON NANOPARTICLES AND THEIR ENVIRONMENT APPLICATIONS IN DEGRADATION OF COLORANTS

Abstract

Abstract:- Iron nanoparticles are recently gaining great interest in environmental remediation circles. Iron nanoparticles (FeNPs) were synthesized by extract of Azadirachta Indica (Neem) leaves. The synthesized particles were characterized by U.V. Visible spectrophotometric and Fourier transforms infrared spectrophotometric technique. The results indicates the highest peak of absorption spectra were obtained at 268 nm wavelength and FT-IR peak at 594 cm-1confirms the formation of zero valent iron nanoparticles. The obtained nanoparticles were then applied as catalyst in degradation of methyl orange (MO) in presence of peroxodisulphate (PDS) as catalyst. The related experiments investigated the removal kinetics and the effect of concentrations of reactants. The loading experiment indicates almost complete removal of dye from water.
