Study of polymer-metal ions triple complex as materials for adsorption andseparation

Diethylenetriamine and a copolymer of sodium acrylate and maleic anhydride were used for the adsorption and separation of Au3+, Ru3+, Bi3+, and Hg2+ i ons by forming polymer-metal lolls triple complex. The acidity, temperature , capacity, and interference on the adsorption of these ions on the complex , as well as the conditions of desorption of these ions from the complex, w ere investigated by means of inductively coupled plasma optical emission sp ectrometry. The results were satisfactory. (C) 1999 John Wiley & Sons, Inc.
