FACILE AND ECO-FRIENDLY METHOD FOR THE SYNTHESIS OF ZINC OXIDE NANOPARTICLES USING AZADIRACHTA AND EMBLICA

The evolution of green chemistry in the production of nanoparticles has wrapped up an immense consideration because traces of chemicals left unreacted in the chemical synthesis process can be precarious. Owing to copious interest a competent protocol for the production of ZnO NPs without calcinations was developed by green synthesis method using aqueous leaf extracts of Azadirachta Indica and Emblica Officinalis. The aqueous leaf extract acts as a solvent with manifold roles as promoter, stabilizer and template for the synthesis of nanoparticle. The formed nanoparticles were characterized by SEM, XRD, FTIR, and EDAX for its morphology, size, crystallinity and percentage composition. The results confirmed the formation of nanoflowers of 51 nm for Azadirachta Indica and nano flakes of 16 nm for Emblica Officinalis. Though both the green synthesis is trendier for nanoparticle synthesis, the biogenic green fabrication of Azadirachta is better due to its morphology, particle size and crystallinity. Green synthesis using Azadirachta is found to be the best stabilizer for synthesizing nanoparticle. And the study was further initiated and reported that Zinc oxide nanoparticle can be used as an inexpensive and effective adsorbent for the removal of arsenic ions from aqueous solution. This approach offers environmentally beneficial alternatives to more hazardous chemicals and processes and promotes pollution prevention by the production of nanoparticle in their natural environs.
