测定汞的方法很多，本文仅就冷原子吸收法测汞的影响因素作一实验探讨。１ 样品前处理过程中影响汞测定的主要因素及干扰排除。１１ 消除试剂引入的干扰：除压力消解法外，其它的消解过程均需大量试剂，并经较长时间才能消解完全。因此，试剂带入的干扰是不可避免的。要消
There are many ways to determine mercury. In this paper, we only make an experimental discussion on the influence factors of mercury in the cold atomic absorption spectrometry. 1 The main factors that affect the determination of mercury in the sample preparation process and interference exclusion. 1 1 to eliminate the introduction of reagent interference: In addition to pressure digestion, other digestion process requires a lot of reagent, and after a long time to digest completely. Therefore, the interference brought by the reagent is inevitable. To eliminate
