Data on the distribution of uranium(IV,VI), plutonium(III) and nitric acid between 30 vol% TBP in dodecane and aqueous nitrate solutions also containing hydrazine nitrate were mathematically described by empirical equations. This made it possible to present distribution ratios of the extracted components as functions of concentrations and temperature at a single variable being varied and other variables being kept constant. Salting-out and self-salting-out action of the electrolytes present in the system as well as mutal replacement of the extracted components from the organic phase are shown.
