Green Synthesis of Copper Oxide Nanoparticles from Papaya/Lemon tea Extract and its Application in Degradation of Methyl Orange

Abstract

Environmental contamination is one of the major and most urgent problems of the modem world. Industries are the greatest polluters, with the textile industry generating high liquid effluent pollutants due to the large amounts of water applied in textile processing. The lowest quantity of synthetic dyes in water can bear upon the aesthetic merit, transparency and gas solubility of water bodies. Nano-metal plays a significant role to minimize the toxicity of water waste due to synthetic dyes. In metal nanoparticles, copper nanoparticles show great catalytic activity. In the present work, degradation of methyl orange would be done by copper oxide nanoparticles. The copper oxide nanoparticles were synthesized by green reduction method using papaya extract and lemon tea extract as a stabilizer. The crystal structure of copper oxide nanoparticles was analyzed by X-Ray diffraction, and SEM was used to determine the particle morphology of nanoparticles.
