Rapidly expanding research in nanotechnology has led to exciting progress in versatile tool of medical and biological applications. The preparation and biological applicability of nobel metal nanoparticles with mono-disperse size distribution and arbitrarily variable size and geometry has attracted considerable interest. In the present work, Magnesium oxide nanoparticles are synthesized by green synthesis method by using magnesium sulphate as a precursor and eco friendly and non toxic aloevera leaf extract as a reducing and stabilizing agent. It was found that magnesium oxide nanoparticles acts as a very good adsorbant and helps in removal of toxic metal ions due to this property its used in water purification. Metal oxide vibrational frequencies and crystalline size of these synthesized nanoparticles were studied using UV-VIS, FTIR, SEM and XRD analysis.
