Abstract A type of polyaniline (PANI) and itaconic acid (IA) with Fe3O4@PANI/IA magnetic nanocomposite was prepared via insitu polymerization method. The Cr(VI) removal potential was examined in this work. Langmuir adsorption isotherm and Freundlich adsorption isotherm experiments was done in batch methods. Some parameters such as pH effect, dosage, contact time, and concentration of solutions were investigated in batch experiments. Structure and morphology of the nanocomposite were well characterized by FT-IR spectra, SEM, TEM, TGA/DTA, VSM, EDS and XRD studies. The results shows that the percentage of Cr(VI) removal (92.2%) has enhanced in PANI with IA nanocomposite. Considering all these results that the Fe3O4@PANI/IA nanocomposites have a promising adsorbent material for the removal of Cr(VI) ion from tannery wastewater.

cobalt (Co2+), lead (Pb2+), ions using metal plating, tannery, mining, dyeing, printing, pigment, lead smelters, and chemical manufacturing industries causes for environmental and water pollution [1]. In general, Chromium exists in the environment as two forms viz, trivalent and hexavalent forms. The chromium (III) is most important to nutrition

conserving glucose levels and risk genotoxicity leads to cancer in human and living organisms. Nature of Chromium (VI) is chronic disorders, mutagenic, teratogenic and toxic against animals and human beings [2]. There are different treatment methods as already available to eliminate the toxic chromium ion such as crystallization, ultrafiltration, reverse osmosis, electro-dialysis, photocatalysis, ion exchange, adsorption, biosorption, and chemical precipitation [3]. Nowadays, nanotechnology produced different types of materials at the nanoscale level which have less than 100 nm [4
