Abstract

The symmetrical type of diamide, N,N,N,N-tetrabutylmalonamide (TBMA) was synthesized, characterized and used for the extraction of uranyl(II) ion from nitric acid media in a diluent composed of 50% 1,2,3-trimethyl benzene (TMB) and 50% kerosene (OK). The effects of nitric acid concentration, uranyl(II) ion concentration, extractant concentration, temperature and salting-out agent (LiNO₃) on distribution coefficients of uranyl(II) ion have been studied. The formation of an 121 uranyl(II) ion, nitrate ion and N,N,N,N-tetrabutylmalonamide complex as extracted species was further confirmed by IR spectra of the saturated extraction of uranyl(II) ion with TBMA, the values the themodynamic functions have also been calculated.
