Mixed oxide nanoparticles of iron and aluminium (FeAlO) were synthesized by combustion process and evaluated for the removal of chromium by adsorption from aqueous solution. The FeAlO were characterized for various physico-chemical properties using x ray diffraction, particle size, SEM, TEM, FTIR analysis. The adsorbent was evaluated to study the effect of different parameters like dose, pH and interference of other ion on removal efficiency. The data was fitted in Langmuir and Freundlich adsorption parameters were computed to determine adsorption capacity. The adsorption isotherm was best fitted for Freundlich adsorption model and adsorption capacity was 0.824mg g-1 for Cr (VI). The FeAlO has good potential for the removal of Cr(VI) from water and wastewater.
