ADSORPTION STUDIES OF CHROMIUM(VI) FROM SYNTHETIC AQUEOUS-SOLUTION BY ACTIVATED CARBON DERIVED FROM BAGASSE

The removal of chromium (VI) from synthetic waste water by adsorption on activated carbon prepared from Bagasse (solid waste produced by sugar industries) was tried to determine the effects of different dosages and different pH. The removal of chromium (VI) from synthetic waste water by adsorption on two types of activated carbon, physical activation and chemical activation (CaCl2 & MgCl2), IRs 0.25, 0.5, 0.75, different pH and different dosages was studied. It was observed that as dosage increases the adsorption increased along with the increase in IR. It was also noted as IR increases the surface area of Bagasse carbon increased. These dosage data were considered in the construction of isotherms. And it was found adsorption follows Freundlich, Langmuir and BET isotherms. The maximum removal of chromium (VI) is obtained at pH 2.0.
