This paper reports the data on the extraction of U(VI), Pu(IV) and Th(IV) from nitric acid by tri-isobutyl phosphate, tri-n-amyl phosphate, tri-isoamyl phosphate and tri-n-hexyl phosphate and provides a comparison of their extraction behaviour with that of tri-n-butyl phosphate. Data on the third phase formation in the system Th(NO[sub 3])[sub 4]-HNO[sub 3]-1.1 M trialkyl phosphate/n-dodecane are also presented. 14 refs., 5 figs., 2 tabs.
