The thermodynamic equation relating DU, the distribution coefficient of uranium (VI) tracer between tri-n-butyl phosphate (TBP) in an inert diluent and nitric acid, to the concentrations of nitric acid and TBP, CH and CT, are evaluated quantitatively. The calculations describe the extraction of nitrates at tracer concentrations by TBP, and chemical reactions which describe the system in the range of 0 to 7 M nitric acid and 0 to 1 M TBP are given. The calculations are compared with experimental data.
