摘　　要：建立了火焰原子吸收光谱法间接测定痕量汞,并对铜(Cu)与汞(Hg)发生置换反应的条件及仪器的操作条件分别进行了优化。该方法中,汞在0.05—4.0μg/mL范围内线性良好,平均回收率在85.1%—100.7%之间,RSD为0.6%—2.2%。In this paper, a method of indirect analysis of trace Hg^2＋ has been developed. The conditions of replacement reaction occurring within Hg^2＋ and Cu^2＋ and operation of apparatus have been optimized respectively. The calibration curve is linear in the range of 0. 05-4. 0μg/mL of Hg^2＋. The recovery is 85.1%-100.7% ,and the RSD is 0.6%-2.2%.
