| Abstract: | Potassium superoxide mixed with potassium hydroxide is an effective oxidizing flux for rock and ore samples. Sodium is not added to the sample and potassium may be removed by precipitation with perchloric acid. Traces of cations with various charges, i.e., Ca2+, Eu3+, and Th4+, are not significantly carried down but silver(I) is partially lost to the precipitate. |
