  • 摘要: 通过EQ3/6程序对Pu在几种高盐地下水中的存在形态进行模拟,发现Pu主要以Pu(Ⅳ)、Pu(Ⅴ)的形式存在.通过静态法实验测定了Pu(Ⅳ)、Pu(Ⅴ)在砂土中的分配系数Kd,比较了Pu(Ⅳ)、Pu(Ⅴ)在砂土介质中不同的吸附行为,并对高盐地下水中Pu吸附行为的影响因素进行初步分析.结果表明,Pu在高盐地下水环境中的存在形式及地质介质矿物组成是影响Pu在高盐地下水中吸附的主要因素.
    Abstract: Sorption process is Sorption of Pu is strongly affected by the form of Pu exist in the natural environment. Many of the research for sorption of Pu is studied but less in single state. We discover that Pu mainly exsit as Pu(Ⅳ) and Pu(Ⅴ) in high salinity groundwater using procedure EQ3/6.Distribution coefficient (Kd) of Pu(Ⅳ) and Pu(Ⅴ) is studied by batch experiments. We will have to compare sorbed behavior of Pu(Ⅳ) with Pu(Ⅴ) and indicate factor which influences sorption of Pu in natural environment. Come to a conclusion,the sorption of Pu is large effected by chemical form of Pu in high salinity groundwater and clay mineral content of soils.
