Breakthrough curves were used to examine the separation of metal ions by the poly (hydroxamic acid) chelating resin. The marked differences of breakthrough points were achieved for mutual separation of metal ions under optimum condition. The effect of a flow rate on the sorption of the metal ions was investigated with copper ion. The flow rate of 0.5 ml min-1 was found the quantitative sorption of metal ions and considering their slopes is expected that highly narrow. The effect of mineral acid on the elution of metal ions from poly (hydroxamic acid) resin has been examined. Preliminary experiments showed that Cu and Fe are almost completely retained by the exchanger in 0.01 M H2S04. In this medium most of the other bivalent ions was readily eluted. Slightly cross-contamination has been observed in all separation. However, it is evident from elution studies that some selective separation is feasible by selection of eluent.
