Adsorption of hexavalent uranium on biomass by-product
(2007)The effectiveness of the uranium removal by olive cake from aqueous solutions has been demonstrated in batch type experiments under normal atmospheric conditions. The adsorption capacity has been evaluated by using both ...

Article
Adsorption of trivalent lanthanides by marine sediments
(2015)The interaction of Eu(III) with two different types of marine sediments has been investigated as a function of various parameters (e.g. pH, [Eu(III)]o, I, humic acid) to evaluate their effect on the Eu(III) adsorption. The ...

Adsorptive removal of U(VI) and Th(IV) from aqueous solutions using polymer-based electrospun PEO/PLLA fibrous membranes
(2013)Fibrous membranes based on poly(ethylene oxide) and poly(l-lactide) fabricated by electrospinning were evaluated for the first time as substrates for the adsorption of tetravalent thorium (Th(IV)) and hexavalent uranium ...

A comparative study of the adsorption of uranium on commercial and natural (Cypriot) sea sand samples
(2013)The adsorption of hexavalent uranium on two different types of sea sand [e.g. a local, Cypriot (N-SS) and a commercially available marine sediment (C-SS)] has been investigated as a function of pH, initial metal concentration, ...

Spectroscopic investigation on the formation of hypochlorite by alpha radiolysis in concentrated NaCl solutions
(1999)The hypochlorite formation induced by alpha radiation in saline solutions is studied by UV/VIS spectroscopy. Experiments are carried out in NaCl solutions of various concentrations between 1 and 5 mol/l and with volume ...

Thorium determination in water samples by liquid scintillation counting after its separation by cloud point extraction
(2011)The aim of this study is the separation and pre-concentration of thorium from aqueous solutions by cloud point extraction (CPE) and its the radiometric determination by liquid scintillation counting (LSC). For CPE, tributyl ...

Uranium adsorption by non-treated and chemically modified cactus fibres in aqueous solutions
(2013)The adsorption efficiency of Opuntia ficus indica fibres regarding the removal of hexavalent uranium [U(VI)] from aqueous solutions has been investigated prior and after the chemical treatment (e.g. phosphorylation and ...

Uranium determination in water samples by liquid scintillation counting after cloud point extraction
(2010)The aim of this study is the radiometric determination of uranium in waters by liquid scintillation counting (LSC) after pre-concentration of the element by cloud point extraction (CPE). For CPE, tributyl phosphate (TBP) ...
