Abstract
Abstract The distributions of neutral atoms in the nitrous oxide–acetylene flame have been measured by nebulizing aquo ions of the following sixteen elements into the flame; cadmium, nickel, zinc, copper, lead, cobalt, manganese, iron, chromium, molybdenum, calcium, tin, gallium, indium, titanium, and boron. The distributions have been figured on the response surfaces on which the changes in distribution are expressed as functions of the flame height and the acetylene flow rate. The response surfaces for the temperature and the OH radical were also investigated. The response surfaces for the atomic absorptions of the elements can be related to the thermodynamic properties of the oxides of the elements. The results have then been used for the discussion of the atomization processes of the elements in the flame. In addition, the sensitivities of absorption spectrometry in the nitrous oxide–acetylene flame have been compared to those in the air–acetylene flame.
