Abstract	이번 실험에서 1차 분리된 희토류 산화물로부터 column chromatography에 의하여 희토류 금속들을 분리해 내고 정량하였다. 희토류 산화물을 Amberlite IR-120 수지에 흡착시킨 다음 EDTA 암모니아 알칼리용액을 사용하여 용출시켰다. 각 분획물중의 희토류금속의 함량을 측정한 결과 Ce가 가장 효과적으로 분리되었고 Nd와 Sm도 부분적으로 분리되었으나 Pr은 전혀 분리되지 않았다. The purpose of this work was to separate Ce, Pr, Nd and Sm from rare-earth oxides by column chromatography. Rare earth solution were adsorbed into the Amberlite IR-120 resin and were eluted by the ammonia alkali solution of the EDTA. As a result of determinating rare earth metals of each fraction, Ce was separated very effectively and Nd and Sm partially separaed but Pr never separated.
