✦ Synopsis

The determination of manganese in iron and steels by u.h.f. plasma torch spcctrometry is described. The intensity of Lhe Mn II 257.16~nm ion line decreased with incrcasinl! concentration of iron, whereas the intensity of the Mn 140X.07-nm atom line increased; only the Mn 1279.48.nm atom line showed constant intensity as the concentration of iron increased. This behavior can be explained in terms of plasma temperature. The effects of acids were examined; the influence of small amounts of diverse elements was depressed by a large amount of iron. A simple and rapid method for the determination of manganese in iron and steels was established, the relative standard deviation being 2.6 Q for 0.10 lo Mn.
