The agricultural by-products such as Rice Straw (RS) has widely investigated as an efficient alternative for current costly methods of removing heavy metals from waste water. RS were modified by CoFe₂O₄, results of adsorption indicated that RS treated with CoFe₂O₄ spinel ferrite nanoparticles appeared to be more efficient to remove heavy metals from waste water. Where the percentage removal of Fe, Mn, are 84.25%, 92.45% respectly and Cu, Cd, Zn, Ni, Pb are 100% removal. The prepared samples were characterized using different analytical techniques, X-ray diffraction (XRD), FTIR, Transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Atomic Absorption Spectrometer (AAS) using in determination of concentrations of heavy metals.
