  In this study, chitosan was prepared from African giant land snail (Archachatina marginata) and acrylamide is grafted onto the chitosan to produce Chitosan Graft Acrylamide (CGA). The two varieties (chitosan and CGA) are separately used as adsorbents for the removal of some heavy metal ions (Pb2+, Cd2+ and Ni2+) from aqueous systems. The amount of metal ions (Pb2+, Cd2+ and Ni2+) adsorbed onto chitosan at optimum temperature( 45°C) ranged from 43.88-60.60, 27.50-58.60 and 41.30-58.90%, respectively. That adsorbed onto CGA ranged from 49.40-65.56%, 56.50-97.90% and 29.60-64.80%, respectively. Results reveal that CGA sorption capacity is approximately twice as high as chitosan.
