| 摘 要： | 按10:1的液土比进行批量吸附实验,结果表明,锶(Sr)在黄土中的吸附很快就能达到平衡;在恒温条件下,黄土中锶的分配系数为55.01L/kg。测定了不同浓度的钙(Ca)对锶吸附的影响,结果表明,钙的存在降低了锶的分配系数。

| Abstract: | In ratio of solution volume to weight of loess 10 to 1,the adsorption experiments were carried out using the batch method.The uptake of Sr was rapid and equilibrium reached balance instaneously.Distribution coefficient is 55.01 L/kg on loess.The influence of Ca2＋ cation on Sr adsorption was studied and the results showed that distribution coefficient of the Sr2＋ decreased with the existence of Ca2＋. |
