Green synthesis of silver nanoparticles using melia azedarach and its characterization, corrosion and antibacterial properties

Abstract

Nanoparticle synthesis by the biological method is economical and environmentally friendly. In the present study, the biosynthesis of silver nanoparticles is performed by using extracts of Melia Azedarach plant leaves. The synthesis is performed by adding to the silver nitrate solution to the leaf extract of Melia azedarach. The color change state the precipitation of nanoparticles of silver. The silver nanoparticles obtained were characterized by various techniques such as X-ray diffraction (XRD), Scanning electron microscope (SEM), transmission electron microscope (TEM), and Energy dispersive spectroscopy (EDX). The XRD analysis shows the particle size of 11 nm calculated by the Debye-Scherrer. The microstructure analysis shows silver particles of spherical and triangular. The corrosion rate was found to be 0.025 mpy. The green silver nanoparticle (AgNPs) synthesized have better antimicrobial potential against both bacteria’s (Bacillus subtilis and Pseudomonas aeruginosa).
