Migration of Uranium (IV)/(VI) in the Presence of Humic Acids in Quartz Sand: A Laboratory Column Study

Autor: Mibus, J., Sachs, S., Nebelung, C., Bernhard, G.

Publikováno v: Journal of Contaminant Hydrology 89 (2007) 199-217 DOI 10.1016/j.jconhyd.2006.08.005

The migration behavior of U(IV)/U(VI) in the presence of humic acids was studied in a laboratory quartz sand system by column experiments. It was found that humic acid influences the transport of U(IV) and U(VI). In presence of humic acid both redox

Clay minerals and organic substances are widespread components of many soils, sediments, and rocks. As humic acids (HA) possess a strong ability for metal complexation, they can influence the migration of radioactive and toxic metal ions in clayey en

Clay minerals and organic substances are common components of many soils, sediments, and rocks. However, little is known on the migration behavior of humic substances in clay formations which is supposed to be governed by diffusion processes. Since h

1st Europaen Chemistry Congress, GDCh, RS*C, sfc, 27.-31.08.2006, Budapest, Hungary

The sorption characteristics of U and Cs on bentonite and montmorillonite were investigated in batch experiments to understand the near-field behaviour in geological nuclear repositories. The pH dependence and the retention of Cs are small and only c

Publikováno v: Bridging Clays, 03.-07.06.2006, Ile d'Oléron, France

Clay minerals and organic substances are common components of soils, sediments, and rocks. Little is known, however, on the migration behavior of humic substances in clay formations. Here, we studied the diffusion of humic acid (HA) in clay at differ
