This paper describes the synthesis of a novel chelating material derived from cellulose, and its heavy metal ions adsorption behavior from aqueous solution. The first section of this paper reports the chemical grafting of cellulose, that aminoacetic acid groups were grafted into the cellulose, resulted a novel yet unreported modified cellulose derivative N,N-(dicarboxymethylaminoethyl, carboxymethyl) aminoethylamine carboxymethyl cellulose amide. This obtained adsorbent was characterized by

In the second section, adsorption behaviors such as kinetic study, adsorption isotherms of the adsorbent for Cu 2+ and Pb 2+ single metal ions from aqueous solution, and adsorption capacity for Ba 2+ , Mg 2+ , Mn 2+ , Co 2+ , Zn 2+ , Pb 2+ , Ni 2+ and Cu 2+ , and the competitive adsorption of this adsorbent between ions were evaluated by ICP spectroscopy.
