Studies have been carried out on the effect of temperature on the extraction of U(VI) from nitric acid medium by tri-n-amyl phosphate/n-dodecane, measured as a function of the extractant concentration and aqueous phase acidity. The results indicate that the extraction is exothermic as in the case of tri-n-butyl phosphate. From the data available an effort has been made to calculate the equilibrium constant, the Gibbs energy change and the entropy changes of the extraction reaction. 21 refs., 3 figs., 4 tabs.
