Thermodynamics of extraction equilibria. Part 5. Correction of the method for the determination of equilibrium constants of extraction processes

Abstract

A previously established method for the determination of extraction constants has been verified for extraction processes in which a 1 : 1 solvate is formed. In the case of formation of a higher solvate, the method has to be corrected so that the extraction equilibria are represented in terms of chemical equivalents. Published distribution data on the extraction of nitric acid and uranyl nitrate with tributyl phosphate are used to illustrate the validity of the method.
