ABSTRACT
Data in Table 7 were obtained by measuring the ratio of the absorbances of the metal solution with and without the addition of a large excess of a salt of an easily ionized metal such as potassium or cesium. This method involves the assumption that the presence of a large am ount of such a salt does not affect the efficiency of vaporization of the metal studied. The results will depend to some extent on the stoichiometry of the flame and the region measured.
