S. Mishra et al., EXTRACTION OF EUROPIUM(III), AMERICIUM(III) AND CURIUM(III) WITH DEHPA AND CYANEX-272, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 34(10), 1995, pp. 843-844
Extraction of Eu(III) is quantitative by 0.03 M DEHPA in xylene from 0
.01 M HNO3 solution, whereas Am(III) and Cm(III) are poorly extracted
under the same condition leading to high separation factors. Cyanex 27
2 does not extract Eu(III), Am(III) and Cm(III) significantly even fro
m 0.01 M HNO3.
