Efficient Coextraction of U(VI), Np(V), and Pu(IV) Using Tetradentate N‑Heterocyclic Amide-Triazine Extractants

The spent nuclear fuel contains significant amounts of actinides in various oxidation states and trivalent lanthanides with strong radioactivity. The development of extractants with strong affinity for different actinides is conducive to improving the economy of nuclear fuels and reducing radioactiv...
