Abstract

The present research work focused on the activated carbon (AC) preparation from dates waste followed by its surface modification by incipient wetness impregnation using different metals: Ca, Co, Mg and Al. The obtained results showed that the AC-Al presented the best removal efficiency of the fluoride. The prepared activated carbons (AC) and (AC-Al) were characterized by several techniques. The optimization study of the AC-Al impregnation conditions was investigated by varying the impregnation time and the Al loading. Batch experiments were carried out to investigate the effect of certain operating parameters on the removal percentage. Several isotherm models were applied.
