A SUMMARY OF THE STUDY ON GRAPHITE FURNACE ATOMIZATION

Some methods used for investigations of mechanism of furnace atomization in recent years have been reviewed in this paper, including thermodynamic method, kinetic method, atomic absorption spectrometry(AAS), X-ray diffraction spectrometry(XRD), X-ray photelectron spect-roscopy(XPS), auger electron spectroscopy(AES), scanning electron microscopy(SEM), molecular absorption spectroscopy(MAS) as well as mass spectroscopy(MS), Each method possesses its advantages and disadvantages. It will be good for the investigations to combine different methods, especially combining theorical methods with experimental methods.
