A kind of chelating cellulose with amino, carboxyl and other ligands were synthesized through stem grafting N-(carbamoylmethyl) iminodiacetic acid(ADA) on the molecular structure of cellulose. Its adsorptive performance and mechanism were studied in detail. ADA chelating cellulose had amnion and carboxyl groups on its molecular structure. Through the infrared spectroscopy analysis on ADA chelated cellulose,it could be found that absorption peak was significantly widened at the places of 3 200~3 500 cm~(-1),...
