Abstract  

A simple graphical method for determination of thermodynamic equilibrium constants, developed for ion-exchange and solvent extraction processes, was successfully applied to a liquid exchangersystem. Close values of the thermodynamic equilibrium constants for the system uranyl chloride—hydrochloric acid—di-2-ethylhyxyl phosphoric acid—toluene (K=7.8±0.8) were obtained when the ionic strength of the aqueous phase was varied and the concentration of di-2-ethylhexyl phosphoric acid in the organic phase was kept constant, and vice versa.
