Abstract
Studies on removal of Cr(VI) from aqueous solution using activated pomegranate peel carbon have been carried out at 32oC. Various parameters such as initial concentration of adsorbate, pH, adsorbent dosage and agitation time were studied by conducting batch mode experiments. The experimental adsorption data fitted reasonably well to Langmuir and Freundlich adsorption isotherms. The adsorption follows Lagergren first order kinetic model. The thermodynamic parameter enthalpy change (H) suggests exothermic nature of adsorption of Cr(VI) on to activated pomegranate peel carbon.
