The extraction of U (VI) with newly synthesized long chain alkyl amide, N,N-dibutyloctadecanamide (DBODA) , has been studied. The dependence of the extraction on nitric acid concentration, DBODA concentration and temperature from nitric acid solution has been investigated and the extracted species has also been investigated using FT-IR spectrometry. The related thermodynamic functions were calculated. The separation factor between U (VI) and Th (IV) is higher and there is no third phase formation under the conditions studied.
