| 摘 要： | 建立了一个用酸（HF、HCI、HNO3、HCIO4）溶解通古斯地区沉积物样品，以Re为内标元素，用电感耦合等离子体质谱（ICP－MS）测定其中铂族元素的分析方法。方法检出限为0．001－0．06μg/L，回收率大于85％。用该方法分析了9个取自通古斯地区的沉积物样品，发现了Ru、Rh、Pd、Ir、Pt等元素的异常。

| Abstract: | A method for determination of ultra-trace platinum group elements (PGEs) in the sediments near the Tunguska explosion site by inductively coupled plasma mass spectrometry (ICP-MS) was developed. Samples were decomposed with mixed acids (hydrofluoric acid, aqua regia, nitric acid and perchloric acid). The detection limits for PGEs are 0.001～0.06 μg/L.The recoveries of standard additions are better than 85%. Nine sediment samples taken from Tunguska explosion site were determined by this method. And the anomalies of Ru, Rh, Pd, Ir and Pt were found. |
