Abstract
This research study presents the biological method by using the extract from the
waste part of a plant, tuber peel extract of Amorphophallus paeoniifolius. AgNPs
were synthesized by mixing AgNO3 and peel extract. The synthesized nanoparticles
were separated from aqueous solution by centrifugation process followed by decantation.
The time required to complete the synthesis of nanoparticles was 2 hrs.
Characterization of AgNPs were confirmed by applying UV-vis spectroscopy, X-ray
diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR) and Energy
dispersive X-ray spectroscopy (EDS). From UV-vis characterization absorption spectra
were found at 400 nm for AgNPs. XRD data confirmed that both synthesized nanoparticles
were face-cantered cubic in crystalline nature and the average crystallite size
for the assign peaks was 16 nm. FTIR data evaluated the characteristic peaks of
different phytochemical components of tuber peel extract which acted as the reducing
agent and possibly as stabilizing agents. IR spectrum was recorded in the range
of 4000-500 cm-1. The absorption peak at 1296.16 cm-1 symbolized the bending band
of adsorbed water of Ag.
