In situ Chemical Speciation of Uranium in Soils and Sediments by Micro X-ray Absorption Spectroscopy

Uranium oxidation states in the 50-300-um regions of contaminated sediments and other qualitative information concerning uranium bonding environments are inferred using X-ray absorption near-edge structure spectroscopy with microanalytical capabilities.
