Analytical advantages of using electrochemistry for atomic spectrometry

Atomic spectrometry and electrochemistry are usually recognized as independ ent analytical tools used for different purposes. Here, a brief review is g iven of the advantages of using electrochemistry in the various fields of a tomic spectrometry techniques. In the first part, the application of electr ochemical 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 wi th atomic emission plasma sources. The second area of the applications of e lectrochemistry will be directly focused on the graphite furnace AAS where the electrodeposition onto the graphite surface of the atomizer could be us ed for both in situ analyte preconcentration or modification of the surface by noble metals.
