Uranium Removal from Aqueous Solutions by Aerogel-Based Adsorbents—A Critical Review
(MDPI, 2023)
Aerogels are a class of lightweight, nanoporous, and nanostructured materials with diverse chemical compositions and a huge potential for applications in a broad spectrum of fields. This has led the IUPAC to include them ...
Microplastics and disposable face masks as “Trojan Horse” for radionuclides pollution in water bodies – A review with emphasis on the involved interactions
(Elsevier, 2023)
This review article focuses on the interaction of radionuclides (americium-241, uranium-232, radium-226, neptunium-237, cesium-137, iodine-125, strontium-90, thorium-234, and potassium-40) with different microplastics ...
Radioactivity/Radionuclide (U-232 and Am-241) Removal from Waters by Polyurea-Crosslinked Alginate Aerogels in the Sub-Picomolar Concentration Range
(MDPI, 2023)
The removal of radionuclide/radioactivity from laboratory and environmental water samples under ambient conditions was investigated via batch-type experiments using polyurea-crosslinked calcium alginate (X-alginate) aerogels. ...
Actinide Ion (Americium-241 and Uranium-232) Interaction with Hybrid Silica–Hyperbranched Poly(ethylene imine) Nanoparticles and Xerogels
(MDPI, 2023)
The binding of actinide ions (Am(III) and U(VI)) in aqueous solutions by hybrid silica–hyperbranched poly(ethylene imine) nanoparticles (NPs) and xerogels (XGs) has been studied by means of batch experiments at different ...
Europium removal from aqueous solutions by oxidized biochar prepared from waste palm tree fronds
(Elsevier, 2023)
Palm oil is a product of major economic importance worldwide however, palm tree cultivation generates large quantities of palm fronds as waste. In this work, the sorption of Eu3+ from aqueous solutions by oxidized biochar ...
Radiometric analysis of potassium, radium and uranium levels in Brazil nuts
(Springer, 2023)
The paper describes an alternative approach for the determination of uranium, radium-226 and potassium levels in Brazil nuts. Potassium analysis was performed by a NaI detector using 1-gram of nut’s ashes, radium analysis ...
The effect of temperature on the U-232 and Am-241 adsorption by PN6 microplastics in aqueous solutions
(Global NEST, 2023)
The effect of temperature on the adsorption of U-232 and Am-241 by PN6 has been investigated in laboratory and environmental water samples (e.g. seawater and waste water) in the picomolar concentration range. Generally, ...
Polonium removal from waters by silver-coated Luffa Cylindrica biochar fibers
(Springer, 2023)
The sorption of ultra-trace levels of polonium by Luffa Cylindrica biochar fibers has been investigated in de-ionized water and seawater samples prior and after surface modification (Ag-coating) of the adsorbent. The effect ...
Effective Th(IV) adsorption by oxidized biochar prepared from palm tree fibers
(Springer, 2023)
The removal of Th(IV) from aqueous solutions by oxidized biochar fibres derived from palm tree fibers has been investigated at pH 3 and under ambient conditions by batch type experiments and FTIR spectroscopy. The experimental ...
Uranium desorption from microplastic surfaces
(Springer, 2023)
The desorption of uranium from microplastic surfaces has been investigated as a function of pH in aqueous solutions under ambient conditions. In addition, the effect of complexing ligands (e.g. EDTA) on the desorption from ...
