We have studied the removal of Cr (VI) ion from aqueous solution at different condition using n-ZVI. The n-ZVI was prepared via borohydrate reduction under inert atmosphere. The effect of temperature, concentration and loading quantities on kinetic and equilibrium of chromium ion removal using n-ZVI were thoroughly examined. The prepared n- ZVI was characterized by several techniques including X-ray diffraction (XRD), transmission electron microscope (TEM) and scanning electron microscope (SEM). The adsorption capacity was found to be 40 mg g-1 at pH 3.9 and 300 K. The pseudo second order was found to be the best fitting kinetic model. The adsorption activation energy was calculated and given to be 41.56 kJ mol-1 . The thermodynamic parameters ∆Go , ∆Ho and ∆So , were also calculated. The results indicate the endothermic and spontaneous nature of the adsorption process.
