| Abstract: | The use of oxazine dyes as redox indicators in the determination of uranium(VI), copper(II), osmium(VIII), iridium(IV) and thallium(III) with iron(II) as reductimetric titrant in phosphoric acid medium has been investigated. The determination of copper in brass and the analysis of the binary mixtures of U(VI) and U(IV), and of Tl(III) and Tl(I) with this reductant and these indicators have been studied. |
