摘要

研究了137Cs与Sumedang粘土作为放射性废物处理系统的天然屏障的相互作用。对于接触时间以及Na和K浓度对137 Cs吸附的影响的实验，Cs的初始浓度为10-8M；然而，由于CsCl浓度的影响，溶液中CsCl的初始浓度范围为10-8至10-3M。分布系数K d被用作样品中137Cs吸附的指标。结果表明，Kd值随Na和K浓度的增加呈非线性下降，也随CsCl浓度的影响呈非线性下降。提出了Freundlich等温线来解释实验中观察到的吸附现象。实验结果表明，溶液中Na+和K+等金属离子的存在以及CsCl浓度的变化对样品对137Cs的吸附有显著影响。在未来评估或选择放射性废物处理设施的场地时，应考虑这些结果。

Interaction of 137Cs with Sumedang Clay as Natural Barrier of Radwaste Disposal

The interaction of 137 Cs with Sumedang clay as a natural barrier for radwaste disposal system has been studied. The initial concentration of Cs was 10 ‑8 M for the experiments on the contact time and the effect of Na and K concentrations on the sorption of 137 Cs; however, the initial concentration ranging from 10 ‑8 to 10 ‑3 M of CsCl in the solution for the effect of CsCl concentration. The distribution coefficient K d is used as the indicator of 137 Cs sorption into samples. It was found that the K d values decreased nonlinearly with the concentration of Na and K, and also to the effects of CsCl concentration. A Freundlich isotherm was proposed to explain the sorption phenomena observed in the experiment. Conclusion of the experiments shown that the presence of metal ions such as Na + and K + and variation of CsCl concentrations in the solution have a significant effect on the sorption of 137 Cs to the samples. The results should be taken into account for the assessment or selection of the site of radwaste disposal facility in the future.
