Abstract
Studies have been carried out on the effect of temperature on the extr action of U(VI) from nitric acid medium by tri-n-amyl phosphate/n-dode cane, measured as a function of the extractant concentration and aqueo us phase acidity. The results indicate that the extraction is exotherm ic 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 change of the extraction reaction.
