摘要
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％．
A method for simultaneous determination of trace concentrations of As and Hg in drink have been investigated by continuous flow mode hydride generation and inductively coupled plasma atomic emission spectrometry.The influence of operating conditions on the result of analysis is discussed.The proposed method is sensitive,accurate and easy to operate.The relative standard deviation is less than 5% if the concentration is 0.05～0.1 mg/L.The recovery of standard addition is 87%～100%.
