Separation of U, Pu, Np and Fission Products by Extraction Chromatography
A rapid, single-column extraction chromatographic method using commercially available UTEV A resin has been developed for the separation of uranium, plutonium, neptunium and fission products. Special consideration has been given to the use of reagents that are compatible with robotized equipment to allow automation of the separation process for routine analysis of nuclear materials. The method yields high decontamination factors and recoveries of approximately 90%. Separated fractions can be directly loaded on filaments for subsequent analysis by thermal ionization mass spectrometry or on alpha targets for analysis by alpha spectrometry. UVNis/NIR absorption spectroscopy was used to study the redox reactions between plutonium, neptunium and hydrogen peroxide involved in the separation process.
