environmental issues being faced the world over. Iron powder (IP) was used as an adsorbent to remove Cu(II) and Cr(III) ions from aqueous medium. -200 mesh (-74 micron) particle size of iron powder was used for this experiment. Batch adsorption experiments were conducted. The adsorption were studied on different parameter such as adsorption dosage, contact time, mixing frequency, medium pH and initial adsorbate concentration in aqueous medium for the remediation of Cu(II) and Cr(III) ions in aqueous medium. Experimental adsorption data were successfully modeled with modified and conventional Langmuir and Freundlich isotherm equations. Fe leaching from the adsorbent at lower pH was an issue which, however, could be satisfactorily addressed above pH 6.5. It was found that iron powder has adsorptive properties and can be used as an adsorbent for removal of Cu(II) and Cr(III) ions.
