Abstract
Adsorption studies of cerium ions on activated charcoal were carried out as a function of pH at room temperature. The studies revealed that the maximum adsorption of cerium ions occurs at pH 4. An adsorption mechanism has been discussed in terms of the hydrolyzed cerium ion species formed in solution at different pH values. The data fit the Langmuir and Dubinin–Radushkevich isotherm equations and their corresponding constants were calculated.
