Abstract
The behavior of Am in acidic and basic solutions containing the Fe(CN) 63-/Fe(CN)64- redox system is studied. In mineral acids, K3Fe(CN)6 and Am(III) form the poorly soluble compound AmFe(CN)6, which with time u ndergoes a change owing to radiolytic reduction of Fe(CN)63- to Fe(CN) 64-. In basic solutions of K3Fe(CN)6, Am(III) is oxidized to AmO2+, fo rming the soluble complex (AMO2)3Fe(CN)6, which gradually decomposes t o produce the solid double hydroxide Na2AmO2(OH)3.nH2O. An Am(IV) hydr oxide is formed if [Am] and [K3Fe(CN)6] are equal.
