A hydrolytically stable complexant for minor An separation from Ln in process relevant diluents

The evaluation of bis-1,2,4-triazine complexants containing eight-carbon, alkoxy-functionalized phenyl substituents at the 3,3 '-positions for selective minor actinide extraction in simulated high level waste is reported. The complexant retained chemoselective extraction efficiency of actinides over lanthanides while breaking through the nonpolar diluent solubility and hydrolytic stability barriers that limit many BTP complexants. Thus, we report a BTP complexant that is readily soluble in both kerosene and isooctanol without forming precipitates, emulsions, or third phase after contact with nitric acid and extracts 241Am3+ from 154Eu3+. Separations and spectroscopic data are reported herein. A complexant for chemoselective separation of 241Am3+ from 154Eu3+ in simulated high-level waste is reported. The data advances complexant-based minor An extractions with excellent solubility in process-relevant diluents, high distribution, and good separation.
