Abstract  

A study on solvent extraction of U(VI), Th(IV) and HNO3 from nitric acid media by DEHSO is described. Extraction coefficients of U(VI), Th(IV) and HNO3 as a function of aqueous HNO3 concentration, extractant concentration and temperature have been studied. From the data the compositions of extracted species, equilibrium constants and enthalpies of extraction reaction have been evaluated. Back-extraction of U(VI) and Th(IV) from the organic phase by dilute nitric acid has also been tested. All studies on DEHSO are compared with TBP.
