Adsorption thermodynamic characteristic and kinetics of dissolved chromium from aqueous solutions onto humic acids (HAs) were studied. The results showed that the Freundlich isotherm model described the equilibrium data well. The negative DeltaG degrees confirmed the spontaneity of adsorption process.
