Scale-up of extraction chromatography using DHDECMP for the separation and purification of americium
A combined anion exchange - bidentate extraction chromatography process for separation and purification of americium from Molten Salt Extraction (MSE) residues has been successfully demonstrated on a pilot plant scale. The extraction chromatography process uses DHDECMP (dihexyl-N,N-diethylcarbamoylmethylene-phosphonate) adsorbed on Amberlite XAD-4 resin. The process effectively recovers and purifies americium from impurity elements such as aluminum, calcium, copper, iron, potassium, magnesium, sodium, lead and zinc. A total of 100 g of americium oxide has been recovered. Calorimetry analysis of the product oxide indicates an americium g/g of 0.852. The product oxide contained 96.5% AmO/sub 2/, with a plutonium g/g of 0.00085 and less than 0.5% of any individual impurity element.
