【摘要】 <正> 自从1964年Pierce等人开始研究稀土元素的薄层色谱以来,国外主要有和Specker等人在这方面作了较多的工作,国内陈永熙等人于1983年发表过一篇研究报告。但是用P538作展开剂,进行稀土元素薄层色谱分离的研究还未见报导。P538是单烷基磷酸,其结构为我们应用P538作薄层色谱的展开剂,使单个轻稀土元素以及铕、铽、钬等元素获得了满意的分离。与文献相比,本更多还原

【Abstract】 A thin-layer chromatographic method wast repstrted for the separation of the rare earth elements. Silica gel, starch and ammonium nitrate were used as stationary phase, and monctetradecyl phosphate (P538), ethyl acetate and nitric acid as developers. La, Ce, Pr, Nd and Sm as well as Eu, Tb and Ho can be favourably separated. The R_f values of rare earth tlcments increases with their atomic number.更多还原
