“…Gallium is an important plutonium metal alloying agent, and WDXRF is well established for quantifying the gallium content (Worley, 2002; Worley and Colletti, 2006). This method involves dissolving the plutonium, removing it with ion exchange solid phase extraction (SPE), and quantifying gallium in the eluate.…”

“…Gallium is an important plutonium metal alloying agent, and WDXRF is well established for quantifying the gallium content ͑Worley, 2002; Worley and Colletti, 2006͒. This method involves dissolving the plutonium, removing it with ion exchange solid phase extraction ͑SPE͒, and quantifying gallium in the eluate. Disposition of transuranic ͑TRU͒ waste is expensive; thus, process waste reduction substantially reduces costs as well as complies with environmental management waste minimization goals.…”

To minimize waste, improve process safety, and reduce costs, modifications were implemented to a method for quantifying gallium in plutonium metal using wavelength dispersive X-ray fluorescence. These changes included reducing sample sizes, reducing ion exchange process volumes, using cheaper reagent grade acids, eliminating the use of HF acid, and using more robust containment films for sample analysis. Relative precision and accuracy achieved from analyzing multiple aliquots from a single parent sample were approximately 0.2 and 0.1%, respectively. The same precision was obtained from analyzing a total of four parent materials, and the average relative accuracy from all the samples was 0.4%, which is within programmatic uncertainty requirements.

To minimize waste, improve process safety, and reduce costs, modifications were implemented to a method for quantifying gallium in plutonium metal using wavelength dispersive X-ray fluorescence. These changes included reducing sample sizes, reducing ion exchange process volumes, using cheaper reagent grade acids, eliminating the use of HF acid, and using more robust containment film for sample analysis. Relative precision and accuracy achieved from analyzing multiple aliquots from a single parent sample were ~0.2% and ~0.1% respectively. The same precision was obtained from analyzing a total of four parent materials, and the average relative accuracy from all the samples was 0.4%, which is within programmatic uncertainty requirements.

This annual review of X-ray fluorescence covers developments over the period 2007-2008 in instrumentation and detectors, matrix correction and spectrum analysis procedures, X-ray optics and micro-fluorescence, synchrotron XRF, TXRF, portable XRF and on-line applications as assessed from the published literature. The trend set in previous years continues with an increase in the number of papers published on applications for XRF, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. Earlier literature has not been ignored in that some of Archimedes oldest writing, previously hidden from sight in a medieval prayer book has now been revealed thanks to the power of modern m-SRXRF. X-ray optics now benefit from the use of poly-capillaries systems, equipment portability has been extended to include the TXRF configuration and readers will find several papers on the use of both two and three dimensional imaging to support environmental, geological and biological studies. The writing team would welcome feedback from readers of this review and invite you to complete the Atomic Spectrometry Updates questionnaire on www.asureviews.org. 9 Applications 9.1 Sample preparation 9.2 Geological and industrial minerals 9.3 Environmental 9.3.1 Aerosols and particulates 9.3.2 Consequences of industrial activity 9.3.3 Other environmental studies 9.4 Archaeological, cultural heritage and forensic 9.5 Industrial 9.6 Clinical and biological 9.7 Thin films and coatings 9.8 Chemical state and speciation 10 Abbrevations 11 References
