A multivessel system for the determination of mercury (Hg) by cold-vapor atomic absorption spectrometry (CV-AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) was developed. The performance of the proposed device was tested by determining total Hg in quality-control samples of hair and fishes following acid digestion. Application of the apparatus to the determination of Hg by CV-AAS following alkaline digestion was studied as well. The detection limit obtained for CV-AAS was 0.11 ng/mL and for ICP-AES 1.39 ng/mL. The results show that the system is appropriate to be used in techniques involving cold-vapor generation of Hg.
开发了一种用于通过冷蒸气原子吸收光谱法（CV-AAS）和电感耦合等离子体原子发射光谱法（ICP-AES）测定汞（Hg）的多容器系统。通过酸消解后测定头发和鱼类质量控制样品中的总汞，对所提出装置的性能进行了测试。还研究了该装置在碱性消解后通过CV-AAS测定汞的应用。CV-AAS获得的检测限为0.11 ng/mL，ICP-AES的检测限为1.39 ng/mL。结果表明，该系统适用于涉及汞冷蒸气生成的技术。
