EVALUASI PENGGUNAAN CHEMICAL MODIFIER PADA ANALISIS LOGAM DAN SEMI LOGAM DENGAN GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY
Abstract: 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.
