| Abstract | ||
| A polyacrylamide was prepared by applying the solution technique used for synthesis of organic polymer. It was characterized by different techniques such as elemental analysis , Infrared spectroscopy and thermal analysis .The extracting efficiency of the resin was studied toward several metal ions from their diluted solutions (50ppm) by atomic absorption spectrometry .The effect of pH and treatment time on the chelating efficiency of the resin was examined and the optimum conditions were found, the chelating efficiency of the resin decrease with pH less than 1.5 and from 1.5 to 7.5 above that the resin became soluble. The loading capacities of the resin for Zn2+,Cd2+,Cu2+and Pb2+ ions were found to be 1.40,1.0,0.62 and 0.42 mg ion/gm resin respectively. The recovery efficiency of these ions was also studied as a function of treating time and the pH of the acidic eluent, and it was found to be in the sequence of Zn2+>Cd2+>Cu2+>Pb2+. | ||
