ABSTRACT:

The thermodynamic study was carried to predict the selectivity behaviour of anion exchange resin Indion-102 in chloride form for iodide and bromide ions in solution. The equilibrium constant K values for the ion exchange reactions were calculated at different temperatures from which the enthalpy values were obtained. The equilibrium constant K calculated for Cl –/ I – and Cl - / Br - uni-univalent ion exchange reaction systems were observed to decrease with rise in temperature indicating the endothermic exchange reactions having enthalpy values 3.86 and 6.36 kJ /mol respectively.

KEYWORDS:
