Abstract
A combined anion exchange-extraction chromatography process for the recovery and purification of americium from molten salt extraction residues has been successfully demonstrated on a laboratory and pilot plant scale. The extraction chromatography process uses dihexyl- N, N-diethylcarbamoylmethylenephosphonate sorbed on Amberlite ® XAD-4 resin. The process effectively separates and purifies americium from impurities such as aluminum, calcium, chloride, copper, fluoride, iron, lead, magnesium, plutonium, potassium, sodium and zinc. A total of 100 g of americium oxide was produced during pilot plant testing. The product oxide contained 96.5 wt.% AmO 2, with 0.085 wt.% Pu and less than 0.15 wt.% of any other individual impurity element.
