Abstract
Formation of third phase (second organic phase) due to limiting solubility of tetravalent actinide solvates in organic solvent has been studied in a qualitative manner by several researchers. Quantitative relations for interactions among various solutes for second organic phase formation were not reported in open literature. In this contribution, an empirical model for Pu(IV) third phase formation in biphasic Pu(NO3)4-H2O-HNO3-0.4 M BESO/dodecane system at 298.15 K is reported. This model is similar to Setchenow model for salting in/out. The reported model could accommodate effect of inextractable nitrates and diluent modifiers on the limiting organic concentration of Pu(IV).Keywords
