    Uranium Leaching from Contaminated Soil Utilizing Rhamnolipid, EDTA, and Citric Acid by Sara Asselin, Jani C. Ingram

    Published 2014-01-01
    “…It was determined that rhamnolipid at a concentration of 150 μM was as effective as EDTA but not as effective as citric acid for the removal of soluble uranium. However, the rhamnolipid was only slightly better at removing uranium from the mining soil compared to a purified water control. …”

    Hydrogeology Response to the Coordinated Mining of Coal and Uranium: A Transparent Physical Experiment by Tong Zhang, Xiang He, Kai Zhang, Xiaohan Wang, Yang Liu

    Published 2021-01-01
    “…A slight strata movement below the uranium was observed, and the leaching solution infiltration in the coal mining area was not observed in a short period in the scenario of uranium mining prior to coal; both of those was presented in the scenarios of comining of coal and uranium and coal mining prior to uranium.…”

    Preparation and Mechanical Properties of Cemented Uranium Tailing Backfill Based on Alkali-Activated Slag by Fulin Wang, Guoliang Chen, Lu Ji, Zhengping Yuan

    Published 2020-01-01
    “…Backfilling disposal based on cement solidification is one of the ways to solve the environmental and safe problems of uranium tailing surface stacking. Alkali-activated slag, especially sodium silicate activated geopolymer, has become the preferred cementing material for the uranium tailing backfilling system because of its advantages of corrosion resistance and high strength. …”

    The Effect of Vacuum Annealing of Magnetite and Zero-Valent Iron Nanoparticles on the Removal of Aqueous Uranium by R. A. Crane, T. B. Scott

    Published 2013-01-01
    “…As-formed and vacuum annealed zero-valent iron nanoparticles (nano-Fe0) and magnetite nanoparticles (nano-Fe3O4) were tested for the removal of uranium from carbonate-rich mine water. Nanoparticles were introduced to batch systems containing the mine water under oxygen conditions representative of near-surface waters, with a uranyl solution studied as a simple comparator system. …”

    Silane coupling and mordanting as attachment techniques for pyridylazo and thiazolylazo ligands in the synthesis of adsorbents for uranium in seawater by Grace M Pooley, Mohammad A Adel-Hadadi, Weixing Li, Travis C Dietz, Aaron Barkatt

    Published 2018-05-01
    “…Activated carbon adsorbents modified with azo compounds (4-(2-pyridylazo)resorcinol, 1-(2-pyridylazo)-2-naphthol, 4-(2-thiazolylazo)resorcinol), or with allyl and vinylbenzyl derivatives of 4-(2-thiazolylazo)resorcinol, were observed to be highly effective in removing uranium from seawater and providing high loadings. …”

    Mackinawite partial oxidation to green rust produces a large, abiotic uranium isotope fractionation by Romain Guilbaud, Morten B. Andersen, Helen M. Freeman, Jeffrey Paulo H. Perez, David Uhlig, Liane G. Benning

    Published 2025-02-01
    “…Accurate reconstructions of oxygen levels in such conditions are therefore required, but current geochemical proxies fail in identifying transitional redox conditions. Uranium isotopes are an emerging palaeoredox proxy, as large isotope fractionations are recorded during the reduction of uranium into anoxic sediments. …”
