Synthesis and Characterization of ZnO Nanoparticles via Aloe Vera Extract

In this work, zinc oxide were synthesized by biological method using Aloe vera plant and the water solution of zinc . The detail characterization of the nanoparticles was carried out on different PH value . The samples were examined with an X-ray diffraction device and the results were almost identical to the JCPDS standard. It was also observed that the size of the particles was affected by the basic and acidic medium in a large way, as the results obtained from the Transmission Electron Microscopy The particle sizes ranged from 5nm to 100nm depending on the change of the PH value.
