氢化物发生-原子荧光光谱法三道联测地球化学样品中汞砷锑(铋)

Simultaneous Determination of Trace Hg,As,Sb(or Bi)in Geochemical Samples by Using HG-AFS

利用PF6-3型三道原子荧光光度计同时测定包括汞在内的砷、铋或锑中的3种元素,方法高效、快速,精密度（RSD）低于5%,加标回收率为93.0%-102.0%。适合地球化学样品中痕量汞、砷、锑、铋的同时测定。

By using PF6 3 atomic fluorescence spectrophotometer,three elements of As,Sb,Bi including Hg have been determined simultaneously.This method is efficient and fast.RSD is less than 5%,and the recoveries of standard materials is 93.0%-102.0%.It is suitable for determing trace contents of Hg,As, Sb and Bi in geochemical samples simultaneously.
