Diamylamylphosphonate
WebContact with 30% tributyl phosphate in dodecane reduced americium; it was nevertheless extracted using short contact times. The TBP extraction of AmO22+over a range of nitric acid concentrations is shown for the first time and was found to be analogous to that of uranyl, neptunyl, and plutonyl ions. Cited By WebAug 27, 2024 · Several ligands have been evaluated for Am (VI) extraction including conventional tributylphosphate (TBP) [ 6 ], its more basic analogues dibutylbutylphosphonate (DBBP) [ 5] and diamylamylphosphonate (DAAP) [ 7 ].
