| 摘要: |
| 采用HNO3-H2O2处理样品,Rh作为内标进行基体效应补偿,通过电感耦合等离子体质谱(ICP-MS)法,测定隐伏矿床植物样品中的Ti、Co、Ni、Cu、Zn、Mo、Cd、W、Pb共9种微量元素的含量。结果建立的方法的各元素检出限为0.01~0.50 ng·ml-1,样品分析结果的相对标准偏差为1.32%~6.32%,加标回收率为91.7%~103.5%。建立的方法简便、快速、准确,适用于隐伏矿床植物中微量元素的测定。 |

| Abstract: |
| ICP-MS was applied to simultaneously determine trace elements (Ti,Co,Ni,Cu,Zn,Mo,Cd,W,Pb) plant concealed mineral deposit. The sample was dissolved with HNO3-H2O2 and the matrix effect was corrected by the in-line addition of internal standard. Detection limits of these element were in the range of 0.01~0.50ng·ml-1.The relative standards(RSD) were in the range of 1.32%~6.32%,and the recoveries were in the range of 91.7%~103.5%. The method is quick,accurate,efficient and can be applied to determine trace elements in plant of concealed deposit. |
