Green Synthesis, Characterization and Environmental Application of Copper Oxide Nanoparticle obtained Using Aqueous Extract of Schrebera Swietenioides Roxb.

Abstract

The goal of the present study was to synthesize the nanoparticles using green methodology with the use of the aqueous plant extract of S. swietenioides. The copper oxide nanoparticle has been synthesized using aqueous root extract of S. swietenioides as a green reducing agent and copper sulfate as source of the metal ions. Formation of the nanoparticles in the reaction mixture was preliminary confirmed by the UV-Vis spectroscopy method. The FT-IR analysis of the synthesized nanoparticles shows the involvement of various bioactive functional groups in the formation of nanoparticles. The UV–Vis absorption spectra indicate the characteristic maximum absorption peak at a wavelength of 340 nm. This confirms the formation of nano-sized copper particles. The SEM analysis of the synthesized copper oxide nanoparticles confirms that the particles have mostly spherical shape with rough surfaces and the size of 21-43 nm. The copper nanoparticles in the media of the aqueous root extract of S swietenioides have been studied for their applications in the photo catalytic reduction of pollutant dyes and metals. The synthesized nanoparticles have been characterized and it was proved that the particles were nano-sized and contained high metal percentage.
