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 adsorption of Eu in silty clay was studied by static method, and the effect of various factors on the adsorption of Eu in silty clay was analyzed experimentally. The distribution ratio of Eu in silty clay was experimentally determined. The effect of particle size, pH value, solid-liquid ratio and initial concentration on the sorption distribution ratio was studied. The results show that the partition coefficient of Eu in silty clay is 102 and the adsorption / distribution ratio of Eu increases with the decreasing of the particle size of silty clay. The adsorption / distribution ratio of Eu increases with the increase of pH As the liquid-solid ratio increases, the adsorption-distribution ratio of Eu increases.
