Description
Tasuku Orino and co-authors test a new family of catcher molecules for pulling two metals out of nuclear waste liquid. The waste left after fuel reprocessing is strongly acidic and holds many elements at once. Their 2024 paper studies ligands called DRPDA, built to grip targets in more than one way, which may help them pick out palladium and zirconium.
In tests, the ligands pulled nearly all of both metals from nitric acid into an oily solvent when the catcher was water-shy enough. Swapping the solvent to dodecane, with some octanol added to speed the work, sharpened the split sharply. Both target metals moved across at rates far above those of the other waste parts. The catchers also kept working despite direct contact with the harsh acid, a need for any real cleanup process.
