Many industries like textile, paper, printing, plastic, food and cosmetic are utilising dyestuff to give different colours to their goods. The waste of these industries contain a large amount of dyes which is normally discharged in the drain water without proper treatments. This paper presents the work for the synthesis of iron oxide nanoparticles and their application for the removal of acid red dye form water. The characterization of iron oxide nanoparticles was carried out with SEM, XRD and Vibrating sample magnetometer. The as synthesized iron oxide nanoparticles were used for the efficient removal of acid red dye from water. After the removal of dyes, maghemite nanoparticles can be separated from the water by magnetic separation. The results showed that iron oxide nanoparticles can successfully be employed for the wastewater treatment.Keywords: Iron oxide nanoparticles, adsorption, dye removal, textile wastewater
