Batch adsorption of Fe (Ø) from aqueous solution onto activated carbon prepared by chemical activation process from date palm seeds (ADPSC) was studied. The maximum adsorption capacity (98.56%) was obtained at pH 5 and contact time 80 minutes. The adsorption data indicates that the process follows the pseudo-second-order kinetic model. As well as the thermodynamic data indicate that adsorption processes is endothermic. The values of enthalpy (ÄH°) and activation energy (Ea) indicate that the adsorption process is chemisorption.
