Abstract

Halocarbon vapours (CCl4 and in some cases CF2Cl2) were introduced into an acetylene-air flame at increasing rates while nebulizing individual solutions of alkaline earth elements, iron, manganese, chromium, molybdenum, tin and also magnesium in the presence of aluminium matrix. Following the theory developed by Sugden and Bulewicz dealing with the signal depression caused by the presence of halocarbons, the formation of dichloride species for the alkaline earth metals and also for iron, manganese and chromium could be elucidated. From the anomalous shapes of the Sugden-Bulewicz plots, incomplete solute vaporization is inferred for magnesium in the presence of aluminium. For the latter binary system, an almost complete evaporation of magnesium could be attained at 1.2% volume concentration of CCl4 vapour in the flame.
