研究了连续式氢化物发生－感耦等离子体原子发射光谱法测定饮料中Ａｓ和Ｈｇ的适宜条件，可以用较低的功率（１．１ｋＷ）获得稳定的分析信号．待测元素含量０．０５～０．１ｍｇ／Ｌ时，ＲＳＤ小于５％（１０次测定）；加标回收率８７％～１００％．适用于多种饮料及其他溶液中痕量Ａｓ和Ｈｇ的测定
The suitable conditions for the determination of As and Hg in beverages by continuous hydride generation-inductively coupled plasma atomic emission spectrometry were studied, and stable analytical signals were obtained with lower power (1.1kW). The RSD was less than 5% (10 determinations) when the test element content was 0.05-0.1 mg / L; the recoveries were between 87% and 100%. It is suitable for the determination of trace As and Hg in various beverages and other solutions
