P,P -di(2-ethylhexyl)ethanediphosphonic acid (H2DEH[EDP]) extraction with Th into o-xylene shows no acid or extractant dependency. At low Th concentrations, extraction occurs via bonding with the phosphoryl oxygens, giving the protonated complexes. At high Th concentrations, complexation leads to the release of H" " ions. Furthermore, the lack of acid and extractant dependency leads to the conclusion that the extracted complexes are polymeric in nature under all conditions." ... 

The extraction of U(VI) into oxylene by P,P -di(2-ethylhexyl) ethanediphosphonic acid (H2DEH[EDP]) is slightly more efficient than the methylene counterpart while showing no acid dependency. Extractant dependency analysis indicates a complexation equilibrium that is more complicated than Am(III), although it is believed that both occur via a similar mechanism under some experimental conditions the hydrated U(VI) metal is transferred into the cavity of an aggregated micelle with release of H ions." ...
