摘　　要：为了获取239Pu在粘土中的迁移规律,采用静态法和动态柱法实验对其在粘土的迁移进行了研究。结果表明,粘土对239Pu的吸附能力较强。在实际水流速为0.61cm/d条件下,239 Pu经过150d迁移距离小于0.2cm。与动态实验相比,采用分配系数计算延迟系数偏小,动态实验结果更接近实际。Batch and column experiments are conducted to obtain the migration rules of plutonium in clay. The results show that 239Pu is strong adsorbed on the clay. Under the conditions that water flow rate is 0.61 cm/d, the loaded 2agPu is transported a distance less than 0.2 cm after 150 d. Comparison with the dynamic experiments, the retardation factor calculated by the sorption distribution coefficient is small, the dynamic experimental results is closer to the actual environment.
