ABSTRACT:

The selectivity behaviour of ion exchange resin Indion-102 in chloride form for inorganic anions like iodide and bromide ions was predicted on the basis of thermodynamic data. The equilibrium constant K calculated for uni-univalent ion exchange reaction systems were observed to decrease with rise in temperature indicating the endothermic ion exchange reactions having the enthalpy values 3.86 and 6.36 kJ /mol respectively. The low enthalpy and higher K values for iodide ion exchange reaction indicates more affinity of the resin for iodide ions as compared to that for bromide ions also in the solution.
