Abstract

Mo isotope, one of highly redox-sensitive isotopes, has been shown to be useful tracers of geochemical processes. Many studies for Mo isotope have documented with the help of recently developed analysis tools, but it has not yet been documented in the Korea. In this study, we introduce two-stage column separation method of Mo using column tube (BioRad PolyPrep(R) column, 10 ml) and anion exchange resin (BioRad Resin AG(R) 1-X8, 200-400 mesh). Mo isotope ratios in the solid SRMs (BHVO-2, SDO-1, PACS-2) and liquid SRM (IAPSO) were measured on MC-ICP-MS (Multi-collector Inductively Coupled Plasma Mass Spectrometer) and then compared with reference Mo isotope ratios. Mo isotope ratios in our study overlap with reference Mo isotope ratios within analytical error.

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.
