Direct analysis of solid corrosion products by laser ablation ICP-MS: Method development and the interaction of aqueous uranium, gadolinium and neodymium with Iron Shot and Iron (III) Oxide

摘要

The purpose of this report is to summarize the work and present conclusions of Project Activity Task ORD-RF-03 conducted under cooperative agreement number DE-FC28-04RW12237 between the U.S. Department of Energy and the Nevada System of Higher Education (NSHE). The work was conducted in the Harry Reid Center for Environmental Studies of the University of Nevada Las Vegas from October 1, 2004 to September 30, 2006. The purpose of the study was to develop a method using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for the direct analysis of iron corrosion products, to evaluate its capabilities, advantages, and limitations, and to apply the method to examine the interaction of actinides, and other elements relevant to the long-term geologic storage of nuclear waste, with iron corrosion products. The desired quantification is for specific (targeted) sections of the surface; elemental ratios can be determined from the data if of interest.
