Abstract

Much attention has been paid on nanomaterials in recent years due to their fundamental and technological applications. The physical and chemical properties of nanomaterials have been enhanced because of their surface-to-volume ratio. Spinel ferrite with the general formula of MFe2O4 (M is a divalent cation) have attracted much attention because of their interesting properties. Nickel ferrite (NiFe2O4) nanocrystalline is one of the most important ferrites among other ferrites because of most promising applications in storage devices, microwave devices, gas sensors, ferrofluids, catalysts and adsorbent. The NiFe2O4 nanocrystalline has been synthesized by various methods such as co-precipitation, sonochemical process, polymeric precursor techniques, mechanical alloying, sol–gel, pulsed wire discharge, shock wave, reverse micelles, hydrothermal and ultrasonically assisted hydrothermal processes.In this study NiFe2O4 nanoparticels have been prepared by co-precipitation method over active carbon. The composite nanosized NiFe2O4/active carbon has been used to remove a number of Azo dyes, such as Alizarine Yellow R and Methyl Orange, from water. The study showed that this composite has a high adsorptive activity for these dyes and its tendency for removal of anionic dye and cationic azo dye was higher than the other. The effect of pH on the rate of the adsorption of the dyes by this ferrite composite was also investigated. The adsorption of these azo dyes on free active carbon and free nanoscaled NiFe2O4 was also examined and compared with that of NiFe2O4/ active carbon composite. The obtained results revealed that this composite is a superior adsorbent compared with either NiFe2O4 or active carbon alone.
