Název v původním jazyce

N,N '-diethyl-N,N '-diphenyl-1,10-phenanthroline-2,9-dicarboxamide as an extraordinarily effective extraction agent for trivalent europium and americium

Popis výsledku v původním jazyce

Solvent extraction of microamounts of Eu3+ and Am3+ from water into nitrobenzene by means of a mixture of hydrogen dicarbollylcobaltate (H+B-) and N,N'-diethyl-N,N'-dipheny1-1,10-phenanthroline-2,9-dicarboxamide (L) was studied. The equilibrium data were explained assuming that the species HL+, H2L2+, HL2+, ML23+, and ML33+ (M3+ = Eu3+, Am3+; L = N,N'-diethyl-N,N'-dipheny1-1,10-phenanthroline-2,9-dicarboxamide) are extracted into the organic phase. Extraction and stability constants of the cationic complex species in nitrobenzene saturated with water were determined and discussed. From the experimental results it is evident that this very efficient N,N'-diethyl-N,N'-diphenyl-1,10-phenanthroline-2,9-dicarboxamide receptor for the Eu3+ and Am3+ cations could be considered as a potential extraction agent for nuclear waste treatment.
