DOI: 10.22161/ijeab/2.2.31

Abstract:
An eco-friendly loom has been taking up in the present study to synthesize copper nanoparticles using Cassia auriculata. The leaf extract of Cassia auriculata acts as reducing as well as capping agent. Synthesis of copper nanoparticles was initially confirmed by the visual observation i.e color change (dark green color). The synthesized copper nanoparticles were primarily characterized by UV-vis spectroscopy and Fourier Transform Infrared (FTIR) spectroscopy. Further, the formation of amorphous and crystalline phase was analyzed by X-Ray Diffraction pattern. The size and morphology of the synthesized Copper nanoparticles was characterized by Scanning Electron Microscopy (SEM) and the elemental composition was analyzed by EDAX. The present study is a preliminary investigation to know about the capability of Cassia auriculata to synthesize copper nanoparticles from its salts. The results of the present study confirmed that the leaf extract of Cassia auriculata be capable of recovering copper from printed circuit boards in the form of nanoparticles in near future.
