| 摘 要： | 加入硼氢化物产生氢化物之前，使锑以Ｓｂ（Ｖ）、铋以Ｂｉ（Ⅲ）状态存在，当加入硼氢化钾后仅产生铋的氢化物，从而实现原子荧光光谱法直接测定金属锑中微量铋；基体锑可导致铋的原子荧光强度显著下降，必须采取基体匹配法工作·方法简便，适于锑中０．０００２％～０．００５％铋的测定。

| Abstract: | Before adding KBH_4,Keep Sb as Sb(V),Bi as Bi(Ⅲ)in solution,bismuth hydride is only generated after adding KBH_4 So it is possible to carry out determination of trace bismuth in metallic antimony by hydride generation atomic fluorescence spectrometry(HG-AFS);however the intensity of fluorescence(IF) of bismuth has been reduced obviously due to presence antimony matrix.Bismuth can be determined with matching matrix method.This method is simple and convenient.It can be applied to determine 0.0002%～0.005% Bi in metallic antimony. |
