Lanthanide、HDEHP-impregnated resin、Extraction chromatography、Simulated debris

In this research, the Ln resin ( HDEHP(di(2-rthylhexyl)orthophosphoric acid), Eichrom Tech.) be studied about the adsorption of lanthanide under different concentration of hydrochloric acid. To study the feasibility of separating these lanthanides. The chromatographic experiment in some selected hydrochloric acid’s concentration be holed. Through the experiments, the mutual separation of lanthanide elements was achieved.
