Synthesis of Fe nanoparticles using biological and chemical methods and its application

Abstract

Nanotechnology can be defined as the manipulation of matter through certain chemical, physical, or biological processes to create materials with specific properties, which can be used in particular applications. Ferrous nanoparticles have been synthesized biologically using extract obtained from the plant Phyllanthus acidus. The extract has been added to a solution of ferrous salt and has been incubated for 24 hours at room temperature to facilitate the formation of Fe nanoparticles. Nanoparticles have been synthesized chemically by the reduction of ferrous salt using a strong reducing agent in presence of a stabilizing agent. The synthesis of Fe particles has been confirmed by UV–Vis spectroscopy analysis. The absorption spectra showed the presence of nanoparticles. FTIR analysis has been done to study the changes in organic groups present in the plant extract. FESEM images show size and morphology of synthesized nanoparticles. The photocatalytic activity of synthesized nanoparticles has been studied using certain industrial dyes. Using these nanoparticles, industrial effluent like effluents of dye industry can be treated to degrade toxic dyes.
