Americium(3) oxidation in bicarbonate-carbonate medium by sodium perxenate

Creators

Description

The action of Na4XeO6 on Am(3) in KHCO3, KHCO3+K2CO3 and K2CO3 solution is investigated by the spectrophotometric method. It is ascertained that in 1.5 mol/l solutions (in terms of HCO3-+CO32-) at the concentrations of perxenate comparable with Am concentrates, the latter fastly moves in Am(4)+Am(5)+Am(6) mixture. The mechanism of Am(3) oxidation with perxanate is proposed; it includes reactions of Am(3 with Xe(3) and, probably, with Xe(6). 9 refs
