The formation of Fe-oxyhydroxide colloids resulting from the simulated weathering of chlorite
(CCa-2) was studied in batch experiments. The detected colloids showed a particle diameter …

Chlorite alteration and the U removal capacity of altered chlorite were investigated. Batch
kinetic dissolution tests using clinochlore CCa-2 were conducted for 60 days in aqueous …

During the chemical weathering of the uranium mill tailings, released uranium could be
immobilized by the newly formed secondary minerals such as oxyhydroxides. A deeper …

The homogeneous and heterogeneous formation of ferric iron oxides from acidic solution
(pH 2.06–2.50) has been studied in the presence of chlorite under constant pH conditions …

Sulfidization of iron oxyhydroxides can be accompanied by a release of adsorbed uranium,
thus enhancing the mobility of uranium in systems undergoing a shift in redox conditions …

Carbonate dramatically affects the adsorption of uranium (U (VI)) onto iron hydroxides and
its mobility in the natural environment. Batch tests, zeta potential measurements, and Fourier …

Investigating uranium migration mechanisms related to the weathering of waste rocks is
essential for developing strategies that can address the potential environmental issues …

In oxidizing environments, the toxic and radioactive element uranium (U) is most soluble and
mobile in the hexavalent oxidation state. Sorption of U (VI) on Fe-oxides minerals (such as …

Uranium retention processes (adsorption, precipitation, and incorporation into host minerals)
exert strong controls on U mobility in the environment, and understanding U retention is …

The sorption of U (VI) onto low-grade metamorphic rock phyllite was modeled with the
diffuse double layer model (DDLM) using the primary mineralogical constituents of phyllite …
