Conclusions The adsorbents were highly efficient for the removal of Cr (VI) from water The Cr (VI) uptake was depended on the initial concentration, temperature, adsorbent dose and pH The adsorption process was endothermic in nature Adsorption proceeded by ion exchange mechanism Further experiments are still required to apply the materials for industrial wastewater treatment and to possibly upgrade to magnetic adsorption process © CSIR 2010 Slide 32
