Title: Direct determination of impurities in actinide matrices by inductively coupled plasma-mass spectrometry

Abstract

This document consists of viewgraphs only. The question is raised: can ICP-MS advantages be exploited (and disadvantages mitigated) to facility fuel analysis The following conclusions are drawn: ICP-MS has attractive features for actinide analysis: detection limits below 1 ppM are easily attainable, short-term relative precision is better than 10%, and judicious calibration gives <20% relative accuracy.

  • Direct sampling of solids is very useful in trace-level analysis, because sample preparation procedures are minimized, and losses of trace elements and introduction of contaminants can be avoided. The objective of this work was to develop a universal methodology for soil analysis by integrating electrothermal vaporization and inductively coupled plasma-mass spectrometry (ETV-ICP-MS) to vaporize solid samples with any inorganic matrix. This methodology required no sample pretreatment and minimized sample size. The rationale was to use chemical modifiers such as CHF{sub 3} to form metal fluorides with much lower boiling points than their other forms (such as oxides and carbides). Givenmore » sufficiently high temperatures and long reaction times, samples in other chemical forms are converted to elemental halides and vaporized. Changing the nature of the sample makes the vaporization process independent of sample matrix. The characterization and application of ETV-ICP-MS for the determination of actinide elements in soil samples will be described. In addition, effects of chemical modifiers, optimization parameters, limits of detection, calibration plots, and matrix effects will be presented.« less
  • The capability to do direct determination of metals in organic matrices by inductively coupled plasma-atomic emission spectrometry was established with equipment available in the Analytical Chemistry Laboratory at ANL. The method was optimized using xylene as the organic solvent, and data on the determination of elements in oils, tri-n-butyl phosphate, and bis-(2-ethylhexyl) hydrogen phosphate reflect satisfactory detectability and precision. Although other solvents can be used, plasma properties are a function of solvent composition; thus, different operating conditions have to be generated. The preparation of standards by serial dilution and solvent extraction techniques was investigated with satisfactory results.
  • Recently there has been much concern with the ability of plants to uptake heavy metals from their surroundings. With the development of instrumental techniques with low detection limits such as inductively coupled plasma-mass spectrometry (ICP-MS), attention is shifting toward achieving faster and more elegant ways of oxidizing the organic material inherent in environmental samples. Closed-vessel microwave dissolution was compared with conventional methods for the determination of concentrations of cerium, samarium, europium, terbium, uranium and thorium in a series of samples from the National Institute of Standards and Technology and from fields in Idaho. The ICP-MS technique exhibited detection limits inmore » parts-per-trillion and linear calibration plots over three orders of magnitude for the elements under study. The results obtained by using nitric acid and hydrogen peroxide in a microwave digestion system for the analysis of reference materials showed close agreement with the accepted values. These values were compared with results obtained from dry- and wet-ashing procedures. The findings from an experiment comparing radiometric techniques for the determination of actinide elements to ICP-MS are reported.« less
