SILVER NANOPARTICLES SYNTHESIS USING DELONIX ELATA FLOWER EXTRACT BY BIOGENIC APPROACH

Abstract

Author(s): Valli G, Suganya M

The importance of Delonix elata flower and silver nanoparticles as revealed by various literature
resources, we planned to carry out biogenic synthesis of silver nanoparticles using the Delonix
elata flower extract. Silver nanoparticles were prepared by employing the standard procedure. The
formations of silver nanoparticles from the extracts were identified first by observing the colour
changes. The Delonix elata flower extract colour changed from yellow to dark brown colour during
the formation of silver nanoparticles. The Silver nanoparticles formed were characterized by UV,
FT-IR, XRD and SEM. UV absorbance at 467nm for Silver nanoparticles. The IR spectrum of Silver
nanoparticles showed Ag–O stretching at 408cm-1. On comparing the IR spectra of the extract and
the nanoparticles confirmed that Silver nanoparticles bonded to OH group present in the bioactive
constituents of Delonix elata flower. XRD & SEM analysis of the Silver nanoparticles showed that
the nano particles lies in the range of 10μm sizes and exist in rectangular shape.
