Adsorption study of some inorganic elements on the surface of activated charcoal prepared from ceratonia siliqua

This study included the process of adsorption some inorganicelements known as environmental risk (Cd, Cr, Cb, Pb) its watersolutions on surface activated charcool to ceratonia siliqua . Thepercentage and isothermal curves werecalculated according equation, well effect temperature , pHand particle size adsorbent these elements. Thestudy comparative with naturalceratonia powder. The results showed an optimum conditions atPH=5 partical was 500 μm, while thepercentage ranged from 81% 93%
