Abstract

A new water-soluble N2,N9-bis(2-morpholinoethyl)-1,10-phenanthroline-2,9-dicarboxamide was evaluated as a agent for the AmIII/EuIII separation in solvent extraction systems with tri-n-octylphosphine oxide in kerosene and 3-nitrobenzotrifluoride as the diluents. The system maintains effective AmIII/EuIII separation up to an absorbed radiation dose of 50 kGy. Over 75% of the ligand remained intact at doses up to 20 kGy.
