This exploratory research focused on the adsorption of Sr(II) on the sodium dodecyl sulfate modified palygorskite (SDS/Pal). The ion exchange reactions existed, and the elements Mg, Al, Si and Fe on the Pal were exchanged by element Sr(II). The adsorption process could be well described by the pseudo-second-order kinetics and Langmuir model. The adsorption capacity increased from 24.91 to 61.87 mmol g −1 with the increase of initial concentration from 10.0 to 100.0 mg L −1 . SDS/Pal is potential for the adsorption of Sr(II) from aqueous solution.

十二烷基硫酸钠改性坡缕石的制备及对Sr(II)离子的吸附效果

这项探索性研究的重点是 Sr(II) 在十二烷基硫酸钠改性的坡缕石 (SDS/Pal) 上的吸附。存在离子交换反应，Pal 上的元素 Mg、Al、Si 和 Fe 被元素 Sr(II) 交换。吸附过程可以用拟二级动力学和朗缪尔模型很好地描述。随着初始浓度从10.0 增加到100.0 mg L -1 ，吸附容量从24.91 增加到61.87 mmol g -1 。SDS/Pal 有可能从水溶液中吸附 Sr(II)。
