1 sie 2024 · Here, we present the following key aspects: (i) the factors influencing uranium mineralization, including material sources, transport processes, and precipitation mechanism; (ii) both natural and anthropogenic sources that contribute uranium entry into the soil; (iii) uranium toxicity generated by its radio- and chemo-toxicities; (iv) the toxic ...
7 sie 2024 · Uranyl can be extracted as studtite under visible light via the reaction between the adsorbed uranyl and the photogenerated H2O2 with imine-based Covalent-Organic Framework photocatalysts.
1 lis 2022 · Radiological and environmental risk assessments of uranium require knowledge of its immediate and long-term behaviour in the soil system. To better understand U(VI) behaviour in contaminated soil, a mesocosm experiment was conducted from 2018 to 2021 by amending soil with U(VI).
26 kwi 2019 · It was found that uranium, introduced into the soil as a solution of 238 UO 2 (NO 3) 2, comprises mainly exchangeable forms with soil components in desert-sandy soil and light and typical sierozems, and in meadow soils, the uranium interaction with soil components results in acid-soluble form.
5 lip 2021 · Uranium (U), a highly toxic radionuclide, is becoming a great threat to soil health development, as returning nuclear waste containing U into the soil systems is increased. Numerous studies have focused on: i) tracing the source in U contaminated soils; ii) exploring U geochemistry; and iii) assessing U phyto-uptake and its toxicity to plants.
13 cze 2023 · This review synthesized the available evidence of potential sources of Uranium, remediation techniques, and biogeochemical cycling, and further discussed the impact of soil properties on uranium immobilization based on available literature.
few literature reviews that elucidated the impact of soil and microbial properties on uranium immobilization and remediation methods to overcome U contamina-tion in the natural environment. In this review, we tried to discuss biogeochemical cycling, sources, impact of soil properties on uranium immobilization and dierent
