Analytical advantages of using electrochemistry for atomic spectrometry*

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.
