BIOSIS COPYRIGHT: BIOL ABS. The activated carbon prepared by carbonization of groundnut husk with sulfuric acid followed by thermal activation showed 80% removal of chromium (VI) at optimum pH 2.0 when a minimum chromium (VI) to carbon ratio of 0.00416 was maintained. The above ratio was valid even for higher concentrations of chromium (VI). The adsorption capacities calculated by Freundlich Adsorption Isotherm gave 5.61 mg/g and 3.54 mg/g of chromium (VI) removal at pH 2.0 for distilled and tap waters respectively. The overall rate constants obtained by kinetic experiments indicated that chromium (VI) removal was more as the concentration decreased.
