Uranium speciation in a chalky soil
Résumé
In this article, the speciation and behavior of anthropogenic metallic uranium deposited on natural soil is approached by combining EXAFS (Extended X-ray Absorption Fine Structure), and TRLFS (Time-Resolved Laser-induced Fluorescence Spectroscopy). First, uranium (uranyl) speciation was determined along the vertical profile of the soil and bedrock by linear combination fitting of the EXAFS spectra. It shows that uranium migration is strongly limited by the sorption reaction onto soil
