Bidentate organophosphorus compounds as extractants—I: Extraction of cerium, promethium, and americium nitrates☆
TL;DR: In this article, it was shown that tetraalkyl methylenediphosphonates, dialkyl N,N-dialkyl carbamylphosphonate, and dialkyyl N, N-dialkylcarbamylmethylenephosphoneates are powerful, chelating extractants for cerium, promethium, and americium from solutions of nitric acid.
