Abstract: The atomization mechinism of cadmium and aluminium on the graphite probe surface in the graphite furnace is studied. The result shows that the atomization of cadmium and aluminium on the graphite probe surface originates from the thermolysis of their monooxides. The appearance temperature of Cd and Al is identical with the thermolysis temperature of their oxides respectively. The active energy of atomization is related to the bond energy of M-O of their oxide.
