AFS may be used for determining Se,As,Sb and Bi,Hg in the same mother solution with dual channel analysis of Se and Hg or Bi by means of improving decomposition and pretreatment methods,and detection conditions for geochemical samples.

• 在原子荧光光谱法中,通过改进地球化学样品的分解条件、预处理及测定条件,使硒与砷、锑以及铋、汞能在同一母液中测定,而且实现了硒与汞或铋的双道同时测定。
