Abstract: Atomic spectrometry and electrochemistry are usually
recognized as independent analytical tools used for different purposes.
Here, a brief review is given of the advantages of using electrochemistry
in the various fields of atomic spectrometry techniques. In the first
part, the application of electrochemical preconcentration before the
atomic spectrometry will be addressed and exemplified. Electrochemical
preconcentration could be used with flame atomic absorption spectrometry
(AAS) or graphite furnace AAS as well as with atomic emission plasma
sources. The second area of the applications of electrochemistry will
be directly focused on the graphite furnace AAS where the electrodeposition
onto the graphite surface of the atomizer could be used for both in
situ analyte preconcentration or modification of the surface by noble
metals.
