The paper presents some peculiar aspects of ion exchange behaviour for a strongly basic anion exchange and a sulphonic chelating agent. A potential chelating resin was prepared from a common strongly basic anion-exchange resin used in a water demineralization plant, PUROLITE A600-PL, by treatment with Nitroso R-Salt (NRS). The effect of stirring regime, phase contact time and initial concentration on sorption capacity of ion exchange resin and sorption mechanism have been investigated. The dynamic capacity of resin loaded with NRS was found to be 1.45 mmol NRS /g dry resin.
