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 AMBERLITE IRA 402 (Cl-) - a common strongly basic anion- exchanger,by treatment with Nitroso R-Salt (NRS).The sorption of NRS on resin and some properties of NRS –IRA 402 chelating resin have been studied.Some parameters of ion-exchange equilibrium as the distribution coefficients Kd, ion-exchange constant, uptake percentage R (%) and apparent Gibbs free energy change (NRSClK-G.) have been calculated.
