Reduction and Oxidation Processes of Chromium in Soils
The kinetics of reduction and oxidation of soluble chromium in various soils (peat, clay, sand, and luvi-chromic cambisols) were studied at constant soil moisture and constant temperature. A total of 1500 g of each soil was incubated with different concentrations of aqueous solutions of K2Cr2O7 or CrCl3 [1-1000 μg (g of dry soil)-1]. The total exchangeable chromium and Cr(VI) were analyzed in s...
متن کاملOxidation-reduction transformations of chromium in aerobic soils and the role of electron-shuttling quinones.
Oxidation of Cr(III) and reduction of Cr(VI) can occur simultaneously in aerobic soils, but the mechanisms involved are not well-understood, especially how electron shuttling by redox-active organic acids is involved. A and B soil horizons from three topohydrosequences from the Coastal Plain and Piedmont physiographic provinces of Maryland were chosen to investigate oxidation-reduction transfor...

Publication 1. A. Manceau et al, “Quantitative Zn speciation in smelter-contaminated soils by EXAFS spectroscopy,” Am. J. Sci. (in press, 2000). Figure 3 (top) Soil samples were taken at several depths from a contaminated site. (bottom) Model compounds derived from polarized-EXAFS data at the ESRF and μ-EXAFS data at the ALS provide a good fit with powder-EXAFS spectra from a soil sample, there...
متن کاملOxidation Kinetics of Chromium and Morphological Phenomena
The oxidation kinetics of chromium at 900~ are independent of the oxygen partial pressure. Although this observation gives evidence for a defect mechanism where chromium interstitials account for the chromium transport in the oxide scale, the experimental phenomena do not support one single model. The occurrence of oxide whiskers and oxide ridges are explained by the energy of activation for th...
متن کاملNon-Equilibrium Solidification of Undercooled Metallic Melts
If a liquid is undercooled below its equilibrium melting temperature an excess Gibbs free energy is created. This gives access to solidification of metastable solids under non-equilibrium conditions. In the present work, techniques of containerless processing are applied. Electromagnetic and electrostatic levitation enable to freely suspend a liquid drop of a few millimeters in diameter. Hetero...
