Efectos interelementos en la atomización electrotérmica de Ag y Pb.

Abstract

An energy Ea(1) that varies from 630 to 850 kJ/mol as the mass of Ag increases from 0 to 6,0 μg is obtained for the atomization of Pb. This behavior indicates the formation of clusters, whose size increases proportionally with the mass of Ag. However, it is observed that the atomization of Ag is only affected by the presence of mass of Pb of the order of micrograms. In both cases, the values of energy Ea(2) corresponds to desorption process.
