A novel and simple analytical procedure has been developed for the trace-level determination of lanthanides (rare-earth elements) in uranium-bearing materials by inductively coupled plasma sector-field mass spectrometry (ICP-SFMS). The method involves a selective extraction chromatographic separation of lanthanides using TRU resin followed by ICP-SFMS analysis. The limits of detection of the method proposed is in the low pg g(-1) range, which are approximately two orders of magnitude better than that of without chemical separation. The method was validated by the measurement of reference material and applied for the analysis of uranium ore concentrates (yellow cakes) for nuclear forensic purposes, as a potential application of the methodology.
建立了电感耦合等离子体质谱（ICP-SFMS）测定含铀材料中痕量镧系元素（稀土元素）的新的、简单的分析方法。该方法采用 TRU 树脂对镧系元素进行选择性萃取色谱分离，然后进行 ICP-SFMS 分析。该方法的检出限处于低 pg g(-1)范围，与无化学分离相比，大约提高了两个数量级。该方法通过对标准物质的测量进行了验证，并应用于铀矿浓缩物（黄饼）的核取证分析，作为该方法的潜在应用。
