Il. Garcia et al., GENERATION OF VAPORS FROM SLURRIED SAMPLES FOR THE FAST DETERMINATIONOF AS AND HG IN COAL FLY-ASH AND DIATOMACEOUS-EARTH, Atomic spectroscopy, 14(5), 1993, pp. 144-147
The conditions for the determination of arsenic and mercury in coal fl
y ash and diatomaceous earth samples using the vapor generation-slurry
methodology are discussed. Data for the fraction of the analyte extra
cted into the supernatant as a consequence of the slurry preparation a
re reported. Calibration is performed using aqueous standards. The res
ults agree well with those obtained with procedures based on whole dis
solution of the samples.
