Resumen
An investigation has been
carried out to establish a rapid
method for the determination
of total V, Cd, Ni, Cu, Pb, Fe,
and Mn in atmospheric particulates
using electrothermal atomization
atomic absorption
spectrometry and flame atomic
absorption spectrometry with
slurry sample introduction.
To evaluate the accuracy of the
proposed method, standard reference
material Urban Particulate
Matter NBS 1648 was analyzed
accordingly. Results obtained and
certified values did not show
statistically significant differences.
The precision of the method,
when applied to real samples,
was in the range of 1 to 3%
expressed as RSD %. The results
are compared with a standard
dissolution procedure.
