摘要
在26.0℃~ 43.0℃的温度范围内，分别用不同浓度(0.005 M ~ 0.100 M)的碘化和溴化离子溶液对离子交换树脂Duolite A-113的碘化和溴化形态进行了平衡。碘化物和溴化物离子交换的分配系数Kd值随着外溶液离子浓度的增加而增加;然而，随着温度的升高，计算得到的Kd值减小。同时，碘离子交换的Kd值高于溴离子交换的Kd值。
Behaviour of radioactive iodine and bromine from aqueous solutions on the ion-exchange resin Duolite A-113
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 Kd values calculated for iodide and bromide ion exchanges increase with the ionic concentration of the external solution; however, with a rise in temperature, the Kd values calculated were found to decrease. Also, the Kd values were higher for iodide exchanges than for bromide exchanges.
