Green Synthesis of Psidium guajava Capped Hydroxyapatite Nanoparticles
J. Environ. Nanotechnol., Volume 9, No 3 (2020) pp. 19-23
Abstract
The current research focuses on the synthesis and characterization of hydroxyapatite nanoparticles of 26±5 nm size from Psidium guajava leaf extract with control over dimensions and composition. The reaction occurred very rapidly as the formation of spherical nanoparticles was almost completed within 30 nm. The probable pathway of the green synthesis was suggested. Appearance, crystalline nature, size and shape of the nanoparticles were examined by Scanning Electron Microscopy, Energy Dispersive X-Ray Analysis, Fourier Transform Infrared Spectroscopy and X-Ray Diffraction techniques. A microwave-assisted route was selected for the synthesis of hydroxyapatite nanoparticles to carry out the reaction fast, suppress the enzymatic action and keep the process environmentally clean and green.
