The extraction of sulfuric acid by long chain amines in organic solution has been studied with a view to determining the value of the stability constants of the amine sulfates and bisulfates formed. Uranium sulfate and thorium sulfate were chiefly studied. The formulas of the complexes extractible with amines have been established, as well as the corresponding dissociation constants. For uranium sulfate the formula of the complex depends only on the nature of the amine, whereas for thorium this formula varies with the amine structure. From the formulas determined and the value of the constants calculated, it was possible to establish the best conditions for uranium and thorium extraction and also for a separation of these two elements. Finally an application of this study is made to the determination of uranium in ores, where the separation of uranium by this method is particularly easy and complete. (auth)
