Borate fusion followed by ion-exchange/extraction chromatography for the rapid determination of Pu and U in environmental materials
- Southampton Oceanography Centre (United Kingdom). School of Ocean and Earth Science
A method for actinide determinations has been established which has considerable advantages over currently described procedures. The benefits are rapid sample throughput, good safety features with no compromise in data quality. A borate fusion is used for the sample digestion. Chemical separation is optimized by using a column of anion-exchange resin column stacked on a UTEVA column. Uranium was measured using thermal ionization mass spectrometry with a precision of 0.2% 2 sigma. Pu measurements were made using alpha-particle spectrometry. The procedure has been applied successfully to a wide range of sample types and other actinide elements (Th, Am, etc.) could also be included in the analytical scheme. The method has been thoroughly evaluated by measuring international reference samples. The method lends itself very well to large-scale environmental surveys.
