中文摘要:
      采用王水溶样-等离子体质谱法测定地质样品中砷、锑、铋、银、镉、铟6个元素,探讨了测定过程中对砷、银、镉、铟干扰的消除问题。方法检出限(10SD,μg/g)分别为:砷0.2、锑0.01、铋0.005、银0.01、镉0.01、铟0.005;精密度(RSD,n=12)分别为砷1.3%~3.0%、锑0.65%~2.3%、铋1.2%~2.6%、银3.2%~6.6%、镉3.7%~8.0%、铟1.1%~5.0%;加标回收率分别为砷96.8%~106%、锑102%~108%、铋102%~106%、银99.7%~104%、镉103%~108%、铟97.9%~100%。用拟定方法测定了国家一级标准物质中砷、锑、铋、银、镉、铟,结果与标准值相符。方法适用于岩石、土壤、水系沉积物等地质样品的测定。
英文摘要:
      This paper presents the method for determination of As, Sb, Bi, Ag, Cd and In in geological samples by inductively coupled plasma mass spectrometry(ICP-MS) with aqua regia sample digestion. The elimination of the interference from coexistent elements on the determination of these elements was discussed. The detection limits (10SD, μg/g) are 0.2 for As, 0.01 for Sb, 0.005 for Bi, 0.01 for Ag, 0.01 for Cd and 0.005 for In. The recoveries are 96.8%~106% for As, 102%~108% for Sb, 102%~106% for Bi, 99.7%~104% for Ag, 103%~108% for Cd and 97.9%~100% for In, with the precision (RSD,n=12)of 1.3%~3.0%,0.65%~2.3%,1.2%~2.6%, 3.2%~6.6%,3.7%~8.0% and 1.1%~5.0%,respectively. The method has been applied to the determination of these elements in the National Standard Reference Materials and the results are in agreement with the certified values.
