摘要
通过静态法研究了Eu在粉质粘土中的吸附情况,实验分析了多种因素对Eu在粉质粘土中的吸附性能的影响。实验测定了粉质粘土中Eu的分配比,研究了粒度、水相pH值、固液比和初始浓度对吸附分配比的影响。结果表明,Eu在粉质粘土中的分配系数为102量级,Eu的吸附分配比随粉质粘土粒度的减小而增大;随着水相中pH增大,Eu的吸附分配比增大;随着液固比增大,Eu的吸附分配比增大。
The distribution of europium on silty clay was studied by batch experiments.The factors that affected the absorption experiment were granularity of rock,pH,ratio of solid liquid and concentration.In conclusion,the value of distribution in the rocks was increased while granularity of rock and concentration were decreasing,meanwhile,the pH and ratio of solid to liquid was increased.
