| 摘 要： | 利用实验得到的数据和合理的理论公式,模拟了若干年后放射性核素Eu(Ⅲ)在被压实皂土中的扩散和迁移行为.分析了时间、皂土中水的流速、Eu(Ⅲ)在被压实皂土中的吸附分配系数对Eu(Ⅲ)在被压实皂土中迁移和扩散的影响.计算结果发现,Eu(Ⅲ)在被压实皂土中的迁移主要受水的流速和分配系数的影响.3m厚的皂土可以有效的阻滞Eu(Ⅲ)从皂土扩数到环境中.

| Abstract: | The long term diffusion and migration of radioeuropium in compacted bentonite were simulated by using the experimental data and theoretical equations.Effects of time,water velocity and distribution coefficient on the migration and diffusion of Eu in compacted bentonite were also simulated. The results indicate that the migration of Eu in compacted bentonite is affected mainly by water velocity and distribution coefficient.3m bentonite can effectively prevent Eu from migrating to enviroment. |
