Antibacterial Activity of Biosynthesized Zinc Oxide Nanoparticles Against Bacterial Contamination in Wastewater

Abstract

In this study biosynthesis of zinc oxide via aqueous olive leaves (olea europea) was investigated. The prepared nanoparticles were characterized by different technique which include FTIR to provide information about functional group, XRD to give structure was hexagonal phase, average size was (13.7) (16.4) (17) nm of sample A, B, C of ZnoNPs respectively.FESEM to provide average particles size was 49. 96, 68.87, 76.69 nm of samle A, B, C of ZnoNPs respectively, the shape of nanoparticles was spherical. EDX which give elemental composition of nanoparticles which confirm the presence of Zn element.The antibacterial effect was investigated and confirmed by CFU( colony forming unit). ZnoNPS causing 100% mortality of E –coli and have activity on total count of bacteria.
