Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

Polymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

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

Opportunities for Australia Amid China's Carbon‐Neutral Transition: Input–Output Approach With Analysis of Australian Renewable Potential

Sustainable Development, EarlyView.
ABSTRACT A major transformation in China's energy mix is underway as the country pursues carbon neutrality by 2060, posing significant structural challenges for Australia as a major exporter of carbon‐intensive resources. This study examines the economic impacts of China's decarbonisation on Australia by applying static and dynamic input–output (IO ...

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.
