The adsorption of the cupric ions on bark of dacryodes edulis and mangifera indica was studied under various experimental conditions with an aqueous solution of concentration 63,55 mg/L. The effect of adsorbent dosage, the contact time and the pH of solution was examined. In all cases, the percentage of adsorbed metal increases with the contact time and the adsorbent dosage; it takes two hours of contact time to reach equilibrium with the bark of mangifera indica, whereas one needs of them three hours for those of dacryodes edulis. On the other hand, the effect of pH on the percentage of adsorbed metal is not the same in both cases since the maximum adsorption on the bark of mangifera indica is located between pH 5 and 6, whereas with the bark of dacryodes edulis, the pH is higher than 6. The results obtained showed that the bark of mangifera indica adsorbed the quantities of copper larger than those of dacryodes edulis; the maximum adsorption capacity determined by the interpretation of the model of Langmuir isotherms are 5,85 mg/g for the bark of mangifera indica, and 5,22 mg/g for those of dacryodes eludis.
