DNA nano-pocket for ultra-selective uranyl extraction from seawater
Nature Communications, 2020 The extraction of metals from seawater is an area of great potential; especially for the extraction of uranium. Here, the authors report on the synthesis of a DNA based uranium adsorbent with high selectivity and demonstrate the potential for the DNA ...

Uranium Extraction From Laboratory-Synthesized, Uranium-Doped Hydrous Ferric Oxides
Environmental Science & Technology, 2009 The extractability of uranium (U) from synthetic uranium-hydrous ferric oxide (HFO) coprecipitates has been shown to decrease as a function of mineral ripening, consistent with the hypothesis that the ripening process will decrease uranium lability. To evaluate this process, three HFO suspensions were coprecipitated with uranyl (UO2(2+)) and maintained

Decontamination of Uranium-Contaminated Soil Sand Using Supercritical CO2 with a TBP–HNO3 Complex
Metals, 2015 An environmentally friendly decontamination process for uranium-contaminated soil sand is proposed. The process uses supercritical CO2 as the cleaning solvent and a TBP–HNO3 complex as the reagent.

Polarographic Determination of Uranium by Extraction Separation
Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1971 Uranyl tribenzoate, formed in benzoate-benzoic acid media, was extracted into chloroform in combination with quaternary ammonium salts (DMBPAC, TEBAC and TEPAC) at pH 2.5-5.5 in the ratio of 1:1. The plot of logD against pH indicated third power dependence of pH. Similar plots of logD vs. log[B-] also showed a slope of 3.
