Abstract
The aim of the present study is the removal of Cr(VI) ions by Amberlite IRN150 resin. Batch exchange experiments were carried out to study the effects of pH, temperature, contact time, chromium initial concentration and the presence of competitive ions. The recovery of Cr(VI) ions from the resin was evaluated through desorption experiments. The obtained results show that the removals of Cr(VI) by Amberlite IRN150 resin was fast and endothermic. The exchange capacity estimated by the Langmuir equation was about 75 mg/g at pH 7. The presence of chloride ions had no effect on Cr(VI) removal, while that of sulfate ions led to its decrease. The recovery of Cr(VI) ions from IRN150 resin by KCl solution reached 49%.
