The extraction of nitric acid and uranyl nitrate with N,N-dibutyl-2-ethylhexyl amide (DBEHA) has been studied. The solvates formed in the organic phase are HN03-DBEHA and U02(NO3) 2.2DBEHA with the corresponding complex formation constants 0.05 and 20, respectively. The increase of uranyl nitrate distribution with the increase of nitric acid concentration in the aqueous phase, has been interpreted as the influence of nitrate ions on the extraction equilibrium.
