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.
