Absorption Level

Graphite Furnace Atomic Absorption Spectrometry (GF-AAS) is not a new method in chemical analysis, especially for metals and metalloids, unfortunately there are a lot of laboratories in Indonesia that still not used it correctly, whereas if used it correctly, the method will be an excellent and can be a reference method. This review focus on the kinds of interferences in the GF-AAS such as spectral, physic and chemical interferences and alsoon the use of a lot of kinds of chemical modifier that very important part in analysis by GF-AAS, however it is often unused because of the difficulty. It is noted that highest absorption level from each analyte is different even though used the same modifier and ashing temperature, therefore the selection of chemical modifier is important to find the appropriate modifier for each analyte and their matrixes.Keyword: GF-AAS, spectral interferences, physic interferences, chemical interferences, chemical modifier

Comprehensive Study

A comprehensive study of theoretical atomic absorbances has been made for most analytically useful elements, the only exceptions being the rare earths. These data have been compared with experimentally determined atomic absorbances in many cases. The importance of the low lying energy levels has been emphasized as well as the need for better atomic transition probability data. The choice of analysis line is discussed from both the theoretical and experimental points of view, and tables of relative atomic absorbances are given with their temperature variations where appropriate.
