| 摘 要： | 对氢化物发生-冷原子荧光光谱法测定锌精矿中的汞含量的过程进行了分析。不确定度的主要来源主要为标准溶液的配制、样品称量、定容及重复测定。当锌精矿中汞含量为0.056%时,测量结果表示为0.056（1±0.0839）%。

| Abstract: | Through analysis the progress of determining mercury content zinc concentrate by hydride generation-cold atomic fluorescence spectrometry.The main uncertainty sources were the preparation of standard solution,the weighing process of sample,the constant volume of sample,and the repeatability of determination results.When mercury content in zinc concentrate was 0.056 %,the determination result was 0.056（1±0.0839）%. |
