Gr. Boaventura et al., MULTIVESSEL SYSTEM FOR COLD-VAPOR MERCURY GENERATION - DETERMINATION OF MERCURY IN HAIR AND FISH, Biological trace element research, 60(1-2), 1997, pp. 153-161
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.
