Adsorptive removal of Cr(VI) from aqueous solution by carbon black

This work is presenting data for the efficiency of carbon black for adsorption of hexavalent chromium ions from aqueous solutions. The Cr(VI) ion removal was studied by the batch adsorption technique. The paper is focused on the effect of different temperatures (293, 313 and 333 K) on the adsorption of Cr(VI) ions from aqueous solutions. Equilibrium modeling of the adsorption process was carried out and the equilibrium parameters were determined. Thermodynamic parameters were calculated using the adsorption equilibrium constant. The results suggest that the process is a typical example of exothermic adsorption.
