Abstract

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. Nonetheless, few studies have been performed in South Korea. In this study, we compared two purification methods previously reported using an anion exchange resin ($AG^{(R)}$ MP-1M), developed the best method in our lab environment, and then verified it by measuring Cu isotopic compositions in two USGS geological reference materials (BHVO-2 and BIR-1a). Although all matrix cations causing mass bias were effectively removed through both two methods with the yield of better than 95%, the method using the mixture of HCl and $H_2O_2$ only displays Cu isotopic compositions, in excellent agreement with reported values within the error. The method developed in this study is expected to be commonly applied to earth and environmental sciences.

구리는 생지구화학적인 과정에 필수적인 전이금속으로 최근 질량분석기 및 분석기술의 발달로 인해 구리 동위원소를 이용한 연구가 전 세계적으로 활발하게 진행되고 있으나, 국내에서는 아직까지 구리 동위원소에 대한 분석 및 이를 이용한 연구가 전무한 실정이다. 본 연구에서는 $AG^{(R)}$ MP-1M 음이온 교환 수지를 충진한 칼럼을 이용하여 구리 분리법을 정립하고 이에 대한 신뢰성 검증을 위하여 두 종류의 암석표준물질(BHVO-2, BIR-1a)에 대해서 동위원소 분석을 실시하였다. 본 연구에 사용된 두 가지 분리법 모두 95% 이상의 회수율을 보였으나 HCl과 $H_2O_2$의 혼합산을 이용하여 분리된 구리에 대하여 분석된 동위원소 값이 기존 보고 값과 오차범위 내에서 잘 일치하였다. 본 연구에서 개발된 구리 동위원소 분석법은 향후 환경과학 등 다양한 분야에서 중요하게 활용될 것으로 기대된다.
