Sorption of Cr(VI) from an aqueous solution was studied using the filter cake obtained from the sugar industry at different pH (1 to 6) and initial chromium concentration (100 to 200 mg/L). From the result, it was observed that the percentage chromium removal was found to be decreased with increase in solution pH and the kinetic data fitted very well with the pseudo second order rate equation when compared to the pseudo first order rate equation. The equilibrium data was represented very well with the Freundlich isotherm model when compared to the Langmuir isotherm model.
