Abstract

The extraction behavior of U(VI) from nitric acid medium by a solution of N,N-dimethyl-N,N-diphenylmalonamide (DMPMA) in the ionic liquid, BmimPF6, was studied. The extractability was measured as a function of various parameters such as kinetics, phase ratio, the concentration of DMPMA, nitric acid and sodium nitrate, alkyl chain length of ionic liquid. The extractability from 5 M nitric acid by 0.35 M DMPMA/BmimPF6 was found to be almost 100 %. Slope analysis of the experimental data suggests that the probable molecular structure of the extraction species is [UO2NO3(DMPMA)2]+, and the mechanism likely occurs by a cation exchange mode.
