Activated carbon was self generated and activated in the laboratory using Bombax ceibabark (naturally available starting raw material), which has been abbreviated as ?ACBCB? and characterized using modern techniques like FTIR and SEM. Adsorptive removal of Cr(VI) ions from aqueous solution on the adsorbent (ACBCB) has been studied under varying conditions of contact time, adsorbent dose and pH to assess the kinetic and equilibrium parameters. Maximum adsorption capacity was found to be 97.8% at optimum pH 5.5 and 110 minutes as optimum contact time. The percentage removal of Cr(VI) ions was found to increase with increased adsorbent doses from 1 to 7gm/lit. The adsorption data have been correlated and found that experimental data are well fitted with the Langmuir and Freundlich isotherms. Experimentally obtained appropriate values of sorption parameters derived from Langmuir isotherm like ?Qm?(adsorption efficacy), ?b?(Langmuir constant), R2(Correlation Coefficient square); and the Freundlich constant values(?n? and ?Kf ?) derived from Freundlich isotherm proved that the adsorbent ?ACBCB? under present investigation is the best one for efficient removal of Hexavalent Chromium from contaminated water and thus can have potential applications in the field of pollution control.
