Abstract
The paper presents some peculiar aspects of ion exchange behaviour for astrongly basic anion exchange and sulphonic chelating agent.A chelating resin wasprepared from a common strongly basic anion- exchange resin used in a waterdemineralization plant,AMBERLITE IRA 402 (Cl- ), by treatment with Nitroso R-Salt(NRS).The sorption of NRS on resin and some properties of NRS – IRA 402 chelatingresin have been studied.The capacity of resin loaded with NRS was found to be 1.70mmoles NRS /g. Chelating sorbent exhibits a good stability in acid medium (HCl).
