Journal of Radioanalytical and Nuclear Chemistry, 2007 Extraction of microamounts of europium and americium by a nitrobenzene solution of hydrogen dicarbollylcobaltate (H+B−) in the presence of dibutyl diethylcarbamoylmethylene phosphonate (DBDECMP, L) has been investigated. The equilibrium data have been explained assuming that the complexes HL+, HL22+ ML33+ and ML43+ (M3+ = Eu3+, Am3+) are extracted into

Solvent extraction in the treatment of acidic high-level liquid waste : where do we stand? [PDF]
, 1998 During the last 15 years, a number of solvent extraction/recovery processes have been developed for the removal of the transuranic elements, {sup 90}Sr and {sup 137}Cs from acidic high-level liquid waste. These processes are based on the use of a variety
