The present work explored the use of solid waste fine blue-coke as a feedstock for the preparation of activated blue-coke and its adsorption property of Cr(VI). Chemical activation of this precursor, using KOH as activating agent, was adopted. The properties of activated blue-coke were characterized by N2 adsorption isotherms. The results show that the iodine number is 1202 mg/g, the Brunauer- Emmett-Teller (BET) surface area is 1368.18 m2/g and the total pore volume is 0.6745 cm3/g, when the activated blue-coke prepared at the optimized conditions: KOH/fine blue-coke ratio at 4, 800°C activated temperature, 60 min activated time. The adsorption properties of activated coke on Cr(VI) were discussed. The regression results show that the adsorption kinetics is more accurately expressed as a pseudo second order model. The linear correlation coefficients of the Langmuir and Freundlich isotherms were determined and the results reveal that the Freundlich isotherm fits the experimental results better.Keywords
