산화 환원 환경에 민감하게 분별되는 몰리브덴(Mo) 안정동위원소는 지구화학적 과정을 유추할 수 있는 지시자로 사용될 수 있다. 최근 분석기기의 발달로 Mo 동위원소를 활용한 지질물질 연구가 많이 보고되고 있지만, 국내에서는 Mo 동위원소에 관한 연구가 없었다. 이번 연구에서는 컬럼관(BioRad PolyPrep(R) column, 10 ml)과 음이온 교환수지(BioRad Resin AG(R) 1-X8, 200-400 mesh)를 이용한 두 번에 걸친 컬럼 작업을 통해 Mo을 분리 및 회수하였다. 이 분리법을 이용하여 고체(BHVO-2, SDO-1, PACS-2) 및 액체(IAPSO) 표준시료의 Mo 동위원소 분석을 다검출기 유도결합 플라즈마 질량분석기(Multi-collector Inductively Coupled Plasma Mass Spectrometer; MC-ICP-MS)로 측정한 결과, 측정된 표준물질의 Mo 동위원소 분석값은 참값과 오차 범위 내에서 잘 일치하였다.
