摘要：

HG-AAS of As, Sb, Bi, Se, Sn, Te and Hg in the presence of Cd or Zn salts has been studied. It has been found that there is an interference effect on the AAS signal in the presence of these salts. In each case the interference by Cd salts is stronger than that by Zn salts. The decrease of the Te signal in the presence of Cd salts is considerable.
