During the solvent extraction of metal ions from an aqueous to organic phase, organic-soluble extractants selectively target aqueous-soluble for transport into phase. In case that are also soluble in our recent studies lanthanide ion-extractant complexes at surface solutions suggested complexation phase can hinder process. Here, we investigate a similar phenomenon relevant separation Co(II), Ni(II), and Fe(III). X-ray fluorescence near total reflection tensiometry used characterize ion...
Solvent extraction of trivalent rare earth metal ions by organophosphorus extractants proceeds via binding phosphoric acid headgroups to the ion. Water molecules in tightly bound first hydration shell must be displaced oxygen atoms from headgroups. Here, we use classical molecular dynamics simulations explore event which a fully hydrated Er3+ binds its headgroup. Approach headgroup into region between and second shells leads fast ejection water molecule that is accompanied reordering...

In case that are also soluble in our recent studies lanthanide ion-extractant complexes at surface solutions have suggested complexation phase can hinder process. Here, we investigate a similar phenomenon relevant separation Co(II) and Ni(II) with supporting experiments probe Fe(III) Ni(II). X-ray fluorescence near total...
