Surface catalysis of uranium(VI) reduction by iron(II)

Autor: Emmanuelle Liger, Philippe Van Cappellen, Laurent Charlet

Publikováno v: Geochimica et Cosmochimica Acta. 63:2939-2955

Colloidal hematite (α-Fe2O3) is used as model solid to investigate the kinetic effect of specific adsorption interactions on the chemical reduction of uranyl (UVIO22+) by ferrous iron. Acid–base titrations and Fe(II) and uranyl adsorption experime

N-compound reduction and actinide immobilisation in surficial fluids by Fe(II): the surface FeIIIOFeIIOH° species, as major reductant

Autor: Emmanuelle Liger, Ewen Silvester, Laurent Charlet

Publikováno v: Chemical Geology. 151:85-93

Soluble Fe(II) is an important reductant in anoxic surficial fluids, due to fast redox kinetics of the Fe(II)/Fe(III) couple. However, its availability is limited in neutral and alkaline pH range by the solubility of FeS(s), Fe3(PO4)2, FeCO3(s) and o

Decontamination of TCE- and U-Rich Waters by Granular Iron: Role of Sorbed Fe(II)

Autor: Emmanuelle Liger, Laurent Charlet, P. Gerasimo

Publikováno v: Journal of Environmental Engineering. 124:25-30

Uranium (UO{sub 2}{sup 2+}) and chlorinated aliphatics [tetrachloroethane (PCE) and trichloroethane (TCE)] can be reduced and thus immobilized or degraded, respectively, by the same abiotic mechanism. In this mechanism the reduction reaction is coupl

International audience; The redox properties of FeII adsorbed onto a series of FeIII (oxyhydr)oxides (goethite, lepidocrocite, nano-sized ferric oxide hydrate (nano-FOH), and hydrous ferric oxide (HFO)) have been investigated by rest potential measur
