The use of additives and stabilizers in the solvent extraction of actinides with tertiary amines to control the third phase formation and the Pu valence state introduces new variables in the solvent extraction behavior of these elements. The effect of the separate presence of nitrous acid as a stabilizer and of a long chain aliphatic alcohol as an additive was evaluated for uranyl and plutonium nitrate. Depending on the acidity of the aqueous solution the addition of nitrite to the water phase can depress or enhance the partition coefficients. The addition of a long chain alcohol has only a depressing effect. When the additive and the stabilizer are present at the same time, the partition coefficient is a maximum when equal molar concentration of alcohol and nitrous acid are added to the organic phase. A coherent interpretation of this behavior is given. (auth)
