Binary metal oxides including Fe-Ti and Fe-Mn provide high surface area and specific affinity for heavy metal adsorption from aqueous systems. To date, it has become a hot topic to develop new technologies to synthesize metal oxides, to evaluate their removal of heavy metals based on modern analytical techniques (SEM-EDAX and XRD etc.). The present study mainly focuses on metal oxide preparation, physicochemical properties, adsorption characteristics and their application in Nickel removal. The effects of different condition for example solution pH initial metal ion concentration, contact time and adsorbent dose were studied by batch experiments. Maximum adsorption of Ni(II) was observed at pH 4 for Fe-Ti (54.01%) and Fe-Mn (67.78%) adsorbents. The equilibrium data of the adsorption was well fitted to the Langmuir isotherm. The adsorption process follows the pseudo-second-order kinetic model. The adsorption capacity of Fe-Mn was greater than that of Fe-Ti. According to the experimental results the adsorbent is expected to be an economical product for metal ion remediation of water and waste water.
