火焰原子吸收法测定冰铜中锑和铋

Determination of Sb and Bi in copper matte by flame atomic absorption spectrometry

以酒石酸作络合剂 ,在 5 %的王水介质中 ,采用原子吸收法测定冰铜中锑、铋。锑、铋在 0～ 2 0 μg/mL范围内线性良好。回收率为 90 %～ 10 5 %。

In the medium of 5% HCl-HNO 3 (3+1) containing tartaric acid as complex reagent, Sb and Bi in copper matte were determined by FAAS. The linear relationship was good in the range of 0-20μg/mL for antimony and bismuth. The recoveries were 90%-105%.
