Recently many researchers have reported the biosynthesis of metal nanoparticles by plant leaf extracts and their potential applications. In this research we reported the synthesis of Iron and iron oxide nanoparticles using a rapid, single step, and completely green biosynthetic method employing aqueous black and green tea extracts as both the reducing and capping agent. The black and green tea were employed as a green reducing and stabilizing agents. Produced nanoparticles were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). In this work the application of nano iron oxide as adsorbent for removal of dye pigment from wastewater, was studied too.
