摘要
本文从马丁方程出发对薄层吸附色谱过程中稀土离子的行为机理作了探索,在实验基础上研究五个展开体系对稀土元素 R_M 的影响,论证了展开剂各组分之间的竞争效应,协萃效应及反协萃效应对稀土元素 R_M 世和相邻稀土元素ΔR_M 的影响趋势,同时对如何选择展开剂最佳条件进行了讨论,对目前所用的一些方法作了比较和研究。
Behavior of rare earth ions in thin-layer chromatography is described.The factors affecting R_M of rare earth ions have been studied.The competitive effects and the negative synergistic effects of the components in the developing solvent system are benefical to separation,but the resolution of rare earth ions is descreased when the synergistic effects act between the components of developer.
