چکیده

The precipitation process was used to prepare magnesium oxide (MgO) with magnesium nitrate hexahydrate Mg(NO3)2.6H2O, ammonia, and distilled water. The precursor is Mg Nitrate, the solvent is distilled water and ammonia is used to adjust the pH of the sample. The MgO was characterized by X-ray diffractometer microscopy. Through Scherrer equation and XRD spectroscopy, the mean size of the particle was observed to be 40 nm. The samples had good crystallinity and good orientation (222) direction. The main aim of the magnesium oxide synthesis in this paper is to explore its anti-bacterial quality. The size of the inhibition zone developed during disk diffusion tests and the minimum inhibitory and minimum bactericidal concentration of samples in media were used to test against antibacterial agents. The efficacy of magnesium oxide nanoparticles was evidenced by the fact that the results of bacterial sensitivity of nanoparticles vary according to the type of bacteria i.e. S. aureus and E. coli.
