摘要：
This article is engaged in the research of extractive chromatographic method for the sep-aration of 15 rare-earth elements with P07 （iso-oetel iscetyl phosphate） as stationary phase,silanization porous microbeads silica gel as support, and hydrochoric acid-sodium chloride asmobile phase. The sodium chloride in eluant has accelerated the speed of rare-earth separa-tion. The base line separation can be achieved for all the 15 rare-earth elements. The authorshave proposed a simple and rapid method of determination of the 15 microrare-earth ele-ments in rocks using extractive chronmtographic enriched separation and ICP spectrometrydetermination, and accurate results for rare-earth elements have been obtained.
