Abstract
The effective and economic removal of heavy metals from industrial effluents is one of the important issues globally. Batch adsorption experiments were carried to fix the adsorption dosage and also to find the optimum pH. A thermodynamic study was made on the adsorption of Cr (VI) ions in aqueous solution distinctly by the adsorbents such as activated Acacia Nilotica Shell Carbon. The adsorption of Chromium (VI) ions by activated Acacia Nilotica Shell Carbon increased when temperature was raised up to 60 oC .The thermodynamic study and kinetic models showed that the adsorption of Chromium (VI) ions by the above adsorbents were physical and Endothermic.
