Degradation of Malachite Green by Green Synthesized Copper Nanoparticles by Using Aloe Barbadensis Leaf Extracts by Madiha Batool in ANOAJ in Lupine publishers.
The present study was aimed to account a green synthesis of copper nanoparticle is by interaction of leaf extract and copper salt. The bio-synthesis of nanoparticles put forward a cost free and eco-friendly method of nanoparticle synthesis. Copper nanoparticles were synthesized by using aqueous solution of copper sulphate and extract of Aloe barbadensis. The prepared leaf extract was observed when 1mM copper sulphate solution is added in it. Color change of the reaction mixture was observed from deep blue to colorless and then to brick red and dark red indicating the formation of copper nanoparticles. The synthesized CuO NPs was characterized by using different technique such as UV, IR, XRD, and SEM. ward a cost-free and environmentally suitable method of nanoparticle synthesis. Synthesized CuO nanoparticles with average particle size of 60n. Shape of copper nanoparticles was spherical and cubic and their range was 80-120nm Different functional group in synthesized nanoparticles are examined by FTIR. UV spectrophotometer confirm peak of copper nanoparticle experiments Copper oxide nanoparticles shows maximum absorbance at 272nm. Catalytic activity of synthesized nano particles is also examined on the degradation of malachite green. This catalytic effect of copper oxide nanoparticles can be contributed to its small size.
