| 摘 要： | 研究了不同粒径的珍珠岩对＾８９Ｓｒ的吸附。结果表明，珍珠岩对＾８９Ｓｒ具有较强的吸附能力，饱和吸附率大于９５％；通过振荡能加速珍珠岩对＾８９Ｓｒ的吸附；珍珠岩对＾８９Ｓｒ的吸附率与时间关系由多项指数描述；不同粒径的珍珠岩对＾８９Ｓｒ的吸附率没有明显差异。

| Abstract: | The adsorption of 89Sr by different sized perlitic particles was studies,and also leaching and distribution. Results of experiment show that:The adsorption rate of perlitic particles for 89Sr is strong and the saturated rate was bigger than 95%;and intermittent shaking can speed up the process of adsorption. The relationship between adsorption rate and time can be described by a poly-exponential equation,and there is no difference of the adsorption rate among different sized perlitic particles. |
