Green Synthesis of Silver Nanoparticles Using Tabebuia Aurea Leaf Extract

Abstract

Silver nano particles were synthesized using Tabebuia aurea (TA) leaf extracts as reducing agents and silver nitrate as precursor. This method provides an economic and eco-friendly green synthesis of silver nano particles. Formation of silver nano particles were confirmed by colour change from light brown to dark brown. The aqueous silver ions when exposed to leaf broth were reduced and resulted in the green synthesis of silver nano particles. The bio reduced silver nano particles were characterized by UV-Vis spectrophotometer, SEM and EDX. The absorbance spectrum of aqueous medium containing SNPs showed a peak at around 410440nm.
