摘要

为了研究Cs(I)和Eu（III）在新型铜改性蒙脱土（cu -蒙脱土）上的扩散行为，采用毛细管法进行了实验研究。实验结果表明，随着压实密度和离子强度的增加，扩散速率降低。实验研究进一步采用Archie’s law和Glaus’s model定量评价孔隙度和离子浓度对扩散的影响。该研究为深部地质核废料处置提供了潜在的应用前景。图形抽象

Study on the diffusion behavior of Cs(I) and Eu(III) in Cu-montmorillonite

To investigate the diffusion behaviors of Cs(I) and Eu(III) on a novel copper-modified montmorillonite material (Cu-montmorillonite), experimental investigations were conducted using the capillary method. The experimental results showed that the diffusion decreases with increasing the compaction density and ionic strength. The experimental study further employed Archie's law and the Glaus' model to quantitatively assess the impacts of porosity and ion concentration on diffusion. This work can provide potential applications in deep geological nuclear waste repositories.
