GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES USING Calotropis procera EXTRACT

The green synthesis of silver nanoparticles (Ag-np) using leaves extract from Calotropis Porocera has been investigated. Extract of Calotropis procera was used as both reducing and stabilizing agent instead of the general convention of the use of sodium borohydride solution. Ag-np was characterized using a combination of spectroscopic techniques: Ultraviolet-Visible (UV-VIS) Spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), Scanning and Transmission Electron Microscopy (SEM and TEM), and Energy Dispersive X-ray (EDX). The spectrum from UV-VIS depicted the wavelength for the formation of Ag-np at 420 nm. Both SEM and TEM depicted the morphology and size of the nanoparticles while the elemental analysis and the relative abundance of each element in the nanoparticles were revealed through the EDX. This research gives a clear efficacy and reality of the use of low cost and environmentally benign extract a main precursor in the synthesis of Ag nanoparticles.
