| 摘 要： | 用碘化铵为活化剂降低探样品中多元素的活化能，使其在氩气氛围中形成稳定、小背景的激发状态，再通过目视谱线强度比较法，连续测定化探样品中Sb、As、Pb、Cu、Bi、Mo、Ag、Zn。该方法可以替代原子荧光、原子吸收和极普3种综合方法，对标样GBW07401和GBW7403的8种元素平等测定4次，相对标准偏差小于2．7％。

| Abstract: | Using activity agent NH 4I to reduce the activation energy of polyelement in geochemical samples, and making them inspiriting in state of stable and a small background.By careful comparison on the intensity of spectral lines,Sb,As,Pb,Cu,Bi,Mo,Ag and Zn in geochemical samples were continually determinated.It is the substitute method of atomic absorption spectrometry, atomic fluorescence spectrometry and single scanning oscilopolarography,and make 4 times paralled determination on 8 elements of GBW07401 and GBW07403,the RSD is less than 2 7%. |
