Antibacterial Activity of Biosynthesized of Titanium Dioxide Nanoparticles Against Bacterial Contamination in Wastewater

Abstract

In this study biosynthesis of titanium dioxide via aqueous orange peel extract was investigated. The prepared nanoparticles were characterized by different technique which include FTIR to provide information about functional group, XRD to give structure was anatase phase for Tio2NPs, average size of crystal was (10.7) (13.1) (18) nm of sample A, B, C of TiO2NPs respectively. FESEM to provide average particles size was 35.85, 46.44 ,56.64 nm and shape of nanoparticles was spherical for sample A, B, C of TiO2NPs respectively. EDX which give elemental composition of nanoparticles which confirm the presence of Ti element The antibacterial activity was investigated and confirmed by (colony forming unit). Tio2NPs causing 100% mortality on E-coli in all studied concentration and have activity on total count of bacteria.
