摘要

摘要研究了用磷酸化吡啶溶液从硝酸溶液中萃取 U(VI)、Th(IV)、Am(III)和 Eu(III)的过程。确定了可萃取络合物的化学计量学。就萃取能力而言，这些化合物不如双（二苯基膦酰基）甲烷，但明显优于氨基甲酰基甲基膦氧化物。在从硝酸溶液中萃取 Am(III) 和 Eu(III) 的过程中，磷化吡啶分子中氧化膦基团数量的增加会导致其萃取能力和选择性显著下降。

Extraction Properties of Polyphosphorylated Pyridines in Nitric Acid Media

Abstract

The extraction of U(VI), Th(IV), Am(III), and Eu(III) with solutions of phosphorylated pyridines from nitric acid solutions has been studied. The stoichiometry of the extractable complexes was established. In terms of their extraction ability, these compounds are inferior to bis(diphenylphosphinyl)methane, but they are significantly superior to carbamoylmethylphosphine oxides. An increase in the number of phosphine oxide groups in the molecules of phosphorylated pyridines leads to a significant decrease in their extraction ability and selectivity in the extraction of Am(III) and Eu(III) from nitric acid solutions.
