Many metal ions co-exist in water and they can compete with each other in the adsorption process for the wastewater treatment processes. Consideration of simultaneous removal of metal ions in real/synthetic wastewater through column studies will be useful to implement the results in real scale systems. In this study, iron oxide coated gravel was used to simultaneously remove Fe(II), Ni(II), and Zn(II) in high strength synthetic leachate sample. Column study was performed to determine the kinetics and mechanism of adsorption process. The order of column adsorption capacities calculated from the breakthrough curves was Fe(II)> Zn(II)> Ni(II). Iron oxide coated gravel column studies showed 98% removal for Fe(II), 90% removal for Zn(II) and 78% removal for Ni (II). Desorption studies were conducted to regenerate iron oxide coated gravel. The recovery efficiency was observed to be 99.64 % for Ni(II), 99.54% for Fe(II) and 6.75% for Zn (II) in the first cycles of the adsorption/desorption process The results of this study showed that iron oxide coated gravel is highly effective to simultaneously remove heavy metals from landfill leachate.
