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。
The results of batch adsorption experiments showed that the adsorption of strontium (Sr) in loess could be balanced quickly and the partition coefficient of strontium in loess was 55.01L / kg under constant temperature. The effect of Ca (superscript 2 +) concentration on the strontium adsorption was determined. The results showed that the presence of calcium decreased the partition coefficient of strontium.
