Abstract:
Activated carbon was prepared from blue coke powder by physical activation. The results
show that the specific surface area (BET) is 697.05m2/g, the total pore volume is 0.4569cm3/g and the
average pore size is 2.6221nm. The adsorption properties of Cr( ) onto blue coke powder activated
carbon are discussed from the kinetics and thermodynamics viewpoints. The pseudo-second-order
kinetic model shows the best correlation with experimental data. Langmuir and Freundlich models are
used to fit the equilibrium, and it is indicated that Freundlich best fits these data. The adsorption of
Cr( ) onto blue coke powder activated carbon is found to be an endothermic process in nature.
