Uranium recovery by immobilized and dried powdered biomass: characterization and comparison
(Elsevier Science Bv, 2003)
Immobilized and dried powdered Trametes versicolor and Phanerochaete chrysosporium basidio of spores were used for the recovery of uranium from aqueous solutions. The biosorption of UO22+ ions by the carboxymethylcellulose ...
Thermal behaviour of alumina precursor obtained by the aluminium sulphate-urea reaction in boiling aqueous solution
(Elsevier Sci Ltd, 2003)
An aqueous solution containing 0.1 M Al3+ and excess urea was boiled for 4 h to obtain an alumina precursor precipitate. The precursor precipitate was separated into several portions and each portion was heated at a different ...
