电感耦合等离子体质谱技术在核地质分析中的应用实践

Application Practice of ICP-MS in Nuclear Geology

摘要: 电感耦合等离子体质谱（ICP-MS）技术已有40年发展历史，到目前为止，该方法仍然是无机元素分析领域最具影响力的高灵敏度分析技术。在核地质研究领域，ICP-MS已经成为铀矿地质勘查和高放废物地质处置的核心分析技术，每年为核地质科研生产提供大量的分析测试数据。应用ICP-MS分析的对象涉及水、土壤、沉积物、岩石、矿物、气体和天然类似物等，分析的元素达到70多种。本文总结了本实验室在核地质研究中应用ICP-MS的实践。

Abstract: Although inductively coupled plasma mass spectrometry （ICP-MS） technology has been developed for nearly 40 years, it is still the most influential high sensitivity and high efficiency analysis technology in the field of inorganic element analysis. In the field of nuclear geology, ICP-MS has become the core technology of uranium geological exploration and geological disposal of high-level radioactive waste, providing a large number of analytical test data for nuclear geological research and production every year. The samples for ICP-MS analysis include water, soil, sediment, rock, mineral, gas and natural analogues. More than 70 elements in those samples have been measured in the past years. This paper summarized the application of ICP-MS in nuclear geology in our laboratory.
