The extraction of uranium from acidic sulfate aqueous systems by benzene solutions of tri-n-octylamine sulfate was measured under various conditions of uranium loading, acid activity, suIfate ion concentration, and amine concentration. An equation for the reaction between the annine sulfate-- bisulfate mixture and the uranium is proposed which is consistent with the results. Under conditions of constant acid activity, amine concentration. and low uranium loading, the distributions observed at varying aqueous sulfate levels are shown to lead to estimates of the formation constants for the aqueous uranium mono- and disulfate complexes which are in reasonably good agreemcnt with those reported by Ahrland. The present evidence suggests only very low or negligible proportions of the trisulfate complex at sulfate molarities below one. (auth)
