摘要
MgO nanoparticles were synthesized via wet chemical method by applying different calcinations temperature. The temperature effects on the surface morphology, size of nanoparticles have been reported. The synthesized nanoparticles were characterized and confirmed by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) analysis. It exhibits the increase of crystallinity with sharp intense peak and increase of size with varying morphologies respectively with respect to the increase of calcinations temperature. Antibacterial studies were done on gram positive (S. aureus) and gram negative (E. coli) bacteria by agar diffusion method. The zone of inhibition was found to more for gram positive bacteria compared with gram negative bacteria. Antibacterial property of prepared nanoparticles is decreases with increases of calcinating temperature. Since this method of preparation produced better yield in simple and cost effective way. Hence it can be applied for more production of magnesium oxide nanoparticles.
