| 摘 要： | 稀散元素矿石经HCl-HNO_3-HF-HClO_4消解后,用电感耦合等离子体质谱法(ICP-MS)测定重金属元素Ni、Cu、Zn、Cd、Sb、Pb、Bi的含量。该方法检出限为0.004~0.51μg?g~(-1),相对标准偏差(RSD,n=6)为1.08%~4.67%,分析结果准确可靠,是测定稀散元素矿石中重金属含量的一种较好的分析方法。

| Abstract: | After the scattered elements ore was digested by HCl-HNO3-HF-HClO4 process, heavy metal elements including Ni,Cu,Zn,Cd,Sb,Pb and Bi were determined by ICP-MS. The method's detection limit was 0.004~0.51 μg?g-1, the relative standard deviation (RSD=6) was 1.08%~4.67%, The analysis result is quite accurate and reliable, and it is a good method for determination of heavy metal elements in scattered elements ore. |
