DEGRADATION OF CARBON TETRACHLORIDE USING HYDROPHOBIC GREEN RUST
<p>Hydrophobic green rusts (GR) were produced using aerial oxidation of solutions containing bis (2-ethylhexyl) sulfosuccinate (BIS) and sodium N-lauroylsarcosinate (SNLS), iron (II) sulfate and sodium hydroxide. The synthesis was conduced at constant pH 8.0±0.1 for the duration of 1-3 hrs. …

The Chemodenitrification of Nitrate by Green Rust and Mackinawite and its Geochemical Implications
… was only relevant in the presence of green rust (GR), a layered double hydroxide Fe(II)/Fe(III) mineral. High anion (SO42-/Cl-) concentrations could arrest chemodenitrification, most likely through competition for sorption, and hence electron transfer, sites. Stable N and O isotope …

Observations and assessment of iron oxide nanoparticles in metal-polluted mine drainage within a steep redox gradient, and a comparison to synthetic analogs
… result was the identification of Zn-bearing green rust platelets in the anoxic outflow water. Green rust minerals have only been identified in nature a handful of times, and we believe this work to be only the second to examine naturally occurring green rust using high resolution TEM …

The effect of surface modification on the crystal growth of iron oxides
… to interaction between the acid molecules and Green Rust II, a common intermediate in iron oxide growth. The growth of Fe₃O₄ was found to be sensitive to solution pH, and the form of the iron starting materials. Examination of reaction intermediates by x-ray diffraction showed that other …

Isotopic fractionation of chromium and uranium during abiotic and microbial Cr(VI) reduction and microbial U(VI) reduction
… by Fe(II) phases (Fe(II-doped goethite, FeS, green rust, siderite and sediments from an active barrier) occurring at Permeable Reactive Barriers and by a group of metabolically diverse bacteria (G. sulfurreducens, Shewanella sp. (Neckar River), P stutzeri DCP-Ps1 and D. vulgaris). The results …
