Abstract: The iodide and bromide forms of the ion exchange resin Duolite A-113 were equilibrated separately with respectively labelled iodide and bromide ion solutions of different concentrations, varying from 0.005 M to 0.100 M in the temperature range of 26.0°C to 43.0°C. The distribution coefficient K_d values calculated for iodide and bromide ion exchanges increase with the ionic concentration of the external solution; however, with a rise in temperature, the K_d values calculated were found to decrease. Also, the K_d values were higher for iodide exchanges than for bromide exchanges.
