| 摘 要： | 用动态法测定了铯在某放射性废物处置预选场址土壤中的平衡吸附量,研究了水相pH值、土壤粒度及铯溶液浓度对土壤吸附铯的影响。pH值、溶液浓度越大,土壤平衡吸附量越大;土壤粒度越小,土壤平衡吸附量越大。用常用的吸附动力学方程对实验数据进行了拟合,并对吸附机理进行了探讨。实验结果表明,该放射性废物处置预选场址土壤对铯的最大吸附率为65.9%,吸附性能较差。

| Abstract: | The sorption properties of cesium in the soil of a nuclear waste repository were investigated by column method.The effects of pH value,granularity of the soil,concentration of cesium solution on the sorption properties were also studied.The experiment results show that the equilibrium adsorptive quantity increases with the increasing of pH value and the initial concentration of cesium solution and decreases with the increasing of the grain size of the soil.This has no orderliness between equilibrium adsorpt... |
