Copper is an essential transition metal involving in various biogeochemical processes. With the recent advances in analytical techniques and mass spectrometry, such as MC-ICP-MS, it is possible to measure Cu isotopes, which allows us to understand various biogeochemical processes in detail.

구리는 무엇인가? | 구리(Cu)는 원자번호 29번의 원소로, 주기율표에서 11족(d-블록)에 속하는 전이금속 중 하나이며, 2개의 안정동위원소인 63Cu (69.174%), 65Cu (30.826%)로 구성되어 있다(Shields et al., 1964). | |
무엇으로 인해 정밀한 Cu 동위원소 분석이 가능해졌는가? | , 1964). 최근 분석기술 및 질량분석기(예 : 다검출기 플라즈마 질량분석기; MC-ICP-MS)의 개발로 인하여 정밀한 Cu 동위원소 분석이 가능해져 이를 활용한 생지화학, 우주화학, 광물학, 지각과 마그마 작용등 다양한 연구가 활발하게 진행되고 있다(Li et al., 2009; Albarĕde, 2004; Marĕchal et al. | |
Cu를 완벽하게 분리⋅추출하기 위해 원소 분리법이 선행되어야 하는 예는 무엇인가? | 현재 MC-ICP-MS를 활용하여 분석하고 있는 다른 안정동위원소(Mg, Li, Sr, Zn 등) 분석과 마찬가지로 Cu 동위원소 분석을 위해서는 분석대상물질 내 Cu를 완벽하게 분리⋅추출할 수 있는 원소 분리법이 선행되어야 한다. 예를 들어, 분리된 Cu용액 내에 나트륨(Na)와 마그네슘(Mg)이 존재하게 되면 분석과정에서 아르곤화합물(23Na40Ar+, 25Mg38Ar+)이형성되어 동위원소 분석 시 간섭을 유발한다(Liu et al, 2014a; Larner et al., 2011; Mason et al. |
