摘要：

The retention of copper on a novel chelating ion-exchange resin (Chromotrope-2R immobilized on Amberlite IRA-400 resin) was investigated with a view to its use for the atomic spectrometric determination of the metal ion in tap and sea waters. The resin proved to have good kinetic properties for retention of copper at water flow rates up to 13.5 ml/min. The effect of various ions on the retention of copper was also studied. The chelating resin was used for the quantitative separation of copper from cobalt, nickel, zinc, calcium, magnesium and cadmium. The proposed method allows the determination of copper in tap and sea water at concentration ranges of 2-200 and 2-10 mug/l, respectively.
