Abstract

Abstract Canola meal (CM) was tested for its ability to adsorb Cr3+ ions from solutions. It was noticed that a decrease in the CM concentration resulted in an increase of the metal ions adsorbed per unit weight of the meal. The meal adsorbed more metal when the metal concentrations in the solutions were higher. Chromium adsorption increased with temperature between 4 and 50°C. The pH values between 5 and 7 did not have much effect on the adsorption of metal by the meal. Freundlich and Langmuir isotherm models fit the equilibrium data of Cr3+ reasonably well.
