| 摘 要： | 岩矿样品经混合酸溶解后,在1.2 mol/L HCl介质中,采用巯基棉分离富集其中的Au和Pd,建立了电感耦合等离子体质谱法(ICP-MS)测定Au和Pd的方法.对样品分解、吸附、洗脱条件等进行了研究.实验表明,使用巯基棉分离富集和选择适当的同位素消除了质谱干扰,采用基体匹配法和以Re为内标元素校正了基体效应和仪器波动的影响.Au和Pd的方法检出限为0.13和0.22 ng/g.使用该法分析标准物质,分析结果与认定值一致,相对标准偏差为(RSD,n=9)4.8％～8.3％,可满足岩矿样品的分析测试要求.

| Abstract: | After dissolved with mixed acids,gold and palladium in rock and mineral samples were separated and enriched by sulfhydryl cotton in 1.2 mol/L HCl solution.Consequently,a determination method of gold and palladium by inductively coupled plasma mass spectrometry(ICP-MS) was established.The experiment conditions about sample decomposition,adsorption and elution were discussed.Experiment results showed that the mass spectral interference was eliminated by sulfhydryl cotton separation and enrichment in combinati... |
