ON STUDIES OF ATOMIZATION MECHANISM OF ELEMENTS ON PROBE SURFACE IN THE GRAPHITE FURNACE

The probe atomization is a new technique. In this paper, the investigation resultsof atomization mechanism for 20 elements on probe surface in the graphite furnace were summarized. Among 20 elements studied, elements,of which atomization originates from thermolysis of chlorides and oxides, are An, Pt and Cd, Al, La, Sin, Eu, Ge, Mn and Fe respectively.The atomization of Sr, V, Cr and Mo originates from thermolysis of carbides. The atomizationof Ph, Co and Ni is realized through reduction of oxides by carbon. The atomization of Sboriginates from thermolysis of either chloride or oxides and for Sn and Bi, from thermolysisof either oxides or reduction of oxides by carbon. For differences between our experimentalresults and references, the necessary explanations and discussions were given.
