Removal of Melachite Green Dye by Using Zinc Oxide Nanoparticles Prepared by The Green Synthesis by Using Camellia Sinensis (Green Tea) Leafs Extract by Madiha Batool in ANOAJ in Lupine Publishers

Green synthesis for nanoparticles using microorganisms, enzymes, and plants leaf or plant extracts have been indicated as possible ecofriendly preferences to chemical and physical methods. In this paper, we report the synthesis of zinc oxide particles by green method. Highly stable and hexagonal zinc oxide nanoparticles were produced by using zinc nitrate and green tea leaf extract. Structural, morphological and optical properties of the synthesized nanoparticles have been characterized by using UV–Vis spectrophotometer, FTIR, SEM, and XRD analysis. The synthesis of nanoparticles of zinc oxide was observed by the color changing of the chemical solution. Powder X-ray diffraction and SEM analysis revealed the synthesis of both Zn and ZnO nanoparticles with average particle size of 60nm. Shape of zinc oxide nanoparticles was hexagonal with the range 80-120nm. UV spectra confirmed the presence of zinc oxide nanoparticles. FTIR showed the peaks of zinc oxide nanoparticles as well as the presence of other compounds. Melachite green dye has been removed by using zinc oxide nanoparticles prepared from green tea leaf extract. The green color of the dye was removed up to 70% with the use of reducing agent sodium borohydrate. Removal of melachite green dye was performed. Other applications of zinc oxide nanoparticles in the medicine, pharma, biotechnology and industries were discussed.
