A Remarkable Strategy to Hijack U(VI) from Mixed Metal Ion Solutions Using 1‑Hydroxy-2-pyridone

The present work envisages a chelation driven, facile, selective, and rapid method for uranium­(VI) separation from a (U, Th) mixture using 1-hydroxy-2-pyridone (1,2–HOPO). Herein, U­(VI) was selectively precipitated as the neutral [UO2(HOPO)2(H2O)]·nH2O (orange colored) complex while Th­(IV) and ot...

Description
Summary:The present work envisages a chelation driven, facile, selective, and rapid method for uranium­(VI) separation from a (U, Th) mixture using 1-hydroxy-2-pyridone (1,2–HOPO). Herein, U­(VI) was selectively precipitated as the neutral [UO2(HOPO)2(H2O)]·nH2O (orange colored) complex while Th­(IV) and other metal ions remained in the solution. The pH of the medium played a key role in facilitating the separation process.
