Abstract  

N-dodecanoylpyrrolidine (DOPOD) was synthesized and used for the extraction of nitric acid and uranyl(VI) ions from nitric media in toluene. The effects of nitric acid concentration, extractant concentration, temperature, salting-out agent (LiNO3) have been studied. The main adduct of DOPOD and HNO3 is HNO3·DOPOD. The complex formation of uranyl(VI) ion, nitrate ion and DOPOD (UO2(NO3)2·2DOPOD) as extracted species are further confirmed by IR spectra and the values of thermodynamic parameters have also been calculated.
