A green method for synthesizing iron oxide nanorods within orange peel pith has been developed. Orange functions as both a support and reducing agent ions. The were characterized using scanning electron microscopy, energy dispersive X-ray spectroscopy, transmission microscopy photoelectron spectroscopy. Results of the characterization indicate that is deposited on surface primarily in form iron, iron(II) magnetite. nanoparticles grow to range 20-40 nm diameter. biocomposite was then tested Cr(VI) reduction removal from aqueous solutions, exhibiting removals high 96% concentrations 10 mg/L 76% 50 mg/L, which almost 4 times capacity alone.
