Description

The extraction of Ce(IV) by di-(2-ethylhexyl) phosphoric acid (0.1M HDEHP) was studied as a function of nitric acid concentration. Extraction of Ce(IV) was carried out with the spent fuel solution but a small percentage of Ru was also found to be extracted. Cerium could be selectively stripped from the organic phase with 8M HNO3/30% H2O2 solution. This procedure led to the recovery of 144Ce free of 106Ru. Based on the solvent extraction data, an extraction chromatographic procedure employing HDEHP(40% w/w) loaded on Amberlite XAD-7 as the stationary phase was developed for the isolation of pure, carrier-free 144Ce from the spent fuel solution.
