Abstract
The flame emission spectra of lead and titanium, weak emitters in an oxy-hydrogen flame, have been studied with a view to their analytical applications. Interference effects, especially on the titanium emission band at λ 518 mμ, and methods for eliminating or reducing them, have been investigated. Methods for determining lead and titanium in their respective alloys, by the use of a standard addition technique, have been developed. These methods have been tested on suitable alloys; the results have a reproducibility of ± 4–5% (coefficient of variation). The advantages and the limitations observed in this study have a general bearing on the application of flame photometry to other elements.
