AbstractThis work is concerned with one of application of adsorption from solution .It deals with the study of the ability of selected clay surfaces (Attapulgite , Bentonite and Kaoline ) for the adsorption of iron(III) ion . The target of study is to search for suitable surfaces which posses high activity for the adsorption of iron (III) ion ,and the to use these surfaces for treatment of the pollution of aqueous solution by this heavy metal ion.The technique of Vis- spectrophotometry has been utilized for the determination of the quantity of ion adsorbed by forming a colored complex with NH4SCN (Ammonium thiocyanate ) , construct the relation between the amount of the adsorbate (ion) and the concentration of equilibrium leads to know the adsorption isotherm in different condition of pH ,temperature ,ionic strength ,particles size and adsorbent weight .
