지질시료 중의 전 희토류원소들을 유도결합플라즈마 원자방출분광법을 이용하여 동시 및 개별 정량하였다. 시료는 산처리 및 알칼리 응용으로 분해하고 TOPO(trioctylphosphine oxide)를 이용하여 용매 추출한 다음 HCl 용액으로 역추출하여 군분리하였다. 표준암석 AGV-1에 대한 분석결과는 US Geological Survey 및 다른 문헌상의 결과와 비교하여 양호하였다.

Inductively coupled plasma atomic emission spectrometry was used for the determination of all 14 rare earth elements (REE) in geological materials. Samples were decomposed by using acid digestion followed by alkaline fusion. Group separation of the REE was achieved by solvent extraction with TOPO (trioctylphosphine oxide) and back extraction into HCl. The results for standard rock sample, AGV-1, showed a good agreement with those obtained by US Geological Survey as well as reported values in other articles.
