Photochemical oxidation of Am(III) in bicarbonate-carbonate solutions saturated with N2O
Creators
Description
The effect of UV light on 1.1·10-4 M Am(III) in Na and K bicarbonate-carbonate solutions saturated with N2O is studied by a spectrographic method. In all instances, Am(IV) is the first product formed. It has a characteristic absorption maximum at 370 nm. The initial rate of Am(IV) accumulation is constant in solutions up to [HCO-3] or [HCO-3] + [CO2-3] ∼ 1.5 M. However, the rate decreases at higher concentrations. In solutions at pH 8.4-10, Am(IV) slowly disproportionates. The proposed method enables practically 100% yields to be attained. The disproportionation of Am(IV) accelerates at pH > 10
