Alternative models for predicting the extraction of water and uranyl nitrate in the two-phase system: water-uranyl nitrate-tributyl phosphate-Amsco 125-82
- Georgia Inst. of Tech., Atlanta
Experimental data for the distribution of uranyl nitrate and water between an aqueous phase and an organic phase containing 5 to 100 vol % tributyl phosphate (TBP) in an odorless kerosene-like diluent (Amsco 125-82) have been reexamined by considering alternative models in which competitive equilibria involving water and uranyl nitrate are assumed. These models are compared and contrasted with earlier analyses which assumed the existence of only a single extactive equilibrium in the two-phase system. Although the new models are not quite as accurate as the earlier model for uranium extraction, they contain fewer adjustable parameters, are mathematically simpler, and can be used to help predict the extraction of water as well as uranyl nitrate.
