【摘要】 采用ICP-MS法对北京市二环、三环、五环路边的尘土样品及密云郊区的农田土、山顶土等样品Pt、Rh、Pd的含量进行了研究和测定。结果显示,ICP-MS具有很高的灵敏度,可以检测尘土样品中ng级贵金属含量。对北京市环境尘土样品进行了测定,发现Pt、Rh、Pd元素的含量较高且有明显的相关性。更多还原

【Abstract】 The distribution of Pt, Rh and Pd in Beijing city and suburb was studied by ICP-MS. The detection limits for three metals were in ng/g or pg/ml. The experimental results shown that the level of platinum group elements in Beijing city was obviously higher than that of background earth sample. The concentrations of Pt, Rh and Pd in the dust samples were of obvious correlations.更多还原
