Keywords: Electrothermal atomization | lead | copper | cadmium | interelement effects.

When Pb was atomized in presence of Cd and Cu, it was observed an enhancement in the atomization efficiency and in the atomization energy (Ea(1)). The obtained results suggest an increase in the Pb-Pb interactions, which seems to evidence interelements effects. Thus, in presence of Cu, the atomization of Pb probably occurs through thermal dissociation of a solid solution or by formation of clusters of Pb. This conclusion is consistent with the good correlation observed between the results and the corresponding diagram of phases.
