Journal ArticleDOI
Microscale investigation into the geochemistry of arsenic, selenium, and iron in soil developed in pyritic shale materials
TL;DR: In this article, the distribution and mineralogy of micron-sized mineral aggregates formed in the top horizon of an acid sulfate soil were determined using Synchrotron-based X-ray fluorescence microprobe.
Journal ArticleDOI
Cesium sorption reversibility and kinetics on illite, montmorillonite, and kaolinite.
TL;DR: Investigation of adsorption/desorption of cesium in both binary and ternary experiments to study component additivity and sorption reversibility over long time periods implies that in some cases, slow desorption kinetics rather than permanent fixation may play an important role in apparent irreversible Cs sorption.
Journal ArticleDOI
Stabilization of Plutonium Nano-Colloids by Epitaxial Distortion on Mineral Surfaces
TL;DR: It is reported that intrinsic Pu nanocolloids generated in the absence of goethite or quartz were 2-5 nm in diameter, and both electron diffraction analysis and HRTEM confirm the expected Fm3m space group with the fcc, PuO2 structure.
Journal ArticleDOI
Nature and Rates of Selenium Transformations: A Laboratory Study of Kesterson Reservoir Soils
TL;DR: In this paper, surface and subsurface soils from Se-contaminated Kesterson Reservoir were incubated for 2.5 years at temperatures of 15, 25, and 35°C to measure Se oxidation rates and help identify the most readily oxidizable fractions.
Journal ArticleDOI
Np(V) and Pu(v) ion exchange and surface-mediated reduction mechanisms on montmorillonite.
TL;DR: Results from this study suggest that Pu(V) ion exchange and surface-mediated reduction to Pu(IV) can immobilize Pu or enhance its colloid-facilitated transport in the environment at neutral to mildly acidic pHs.
