摘要

The ion exchange resins Duolite A-116, Indion 830 Type-1 and Indion N-IP Type-2 in iodide form were equilibrated separately with labelled radioactive iodide ion solutions of different concentrations varying from 0.005 M to 0.020 M in the temperature range of 25.0℃ to 40.0℃. The K_d values of iodide ions for Duolite A-l 16 and Indion N-IP Type-2 were higher than that for Indion 830 Type-1 under identical experimental conditions. The difference in the K_d values of iodide ions for the three resins was mainly because of the swelling pressure, which depends on their water-holding capacities.
