Abstract
A multivessel system for the determination of mercury (Hg) by cold-vap or atomic absorption spectrometry (CV-AAS) and inductively coupled pla sma atomic emission spectrometry (ICP-AES) was developed. The performa nce of the proposed device was tested by determining total Hg in quali ty-control samples of hair and fishes following acid digestion. Applic ation of the apparatus to the determination of Hg by CV-AAS following alkaline digestion was studied as well. The detection limit obtained f or 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.
