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 Since Pierce et al began to study the thin-layer chromatography of rare earth elements in 1964, many foreign researchers mainly did work in this respect with Specker et al. In 1983, Chen Yongxi et al. Published a research report. However, the use of P538 as a solvent for the thin layer chromatography of rare earth elements has not been reported. P538 is a monoalkylphosphoric acid. The structure of P538 is that we use P538 as a developing solvent for thin-layer chromatography, so that a single light rare-earth element and elements such as europium, terbium and holmium are satisfactorily separated.
