Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
(
- The open environmental journal
, 2007)
The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: ...
On the validity of specific rate constants (kSA) in Fe0/H2O systems
(
- Journal of hazardous materials
, 2009)
The validity of the specific reaction rate constants (kSA) in modelling contaminant removal in Fe0/H2O systems is questioned. It is shown that the current kSA-model does not consider the large reactive surface area provided ...
Laboruntersuchungen zur Freisetzung von Unat aus einem Gestein unter oxischen naturnahen Bedingungen
(
- Grundwasser
, 2005)
The effects of carbonate concentration and the presence of iron hydroxide phases on uranium release into the environment were investigated under oxic conditions and in the pH range from 6 to 9. For this purpose not-shaken ...
High-Resolution Imaging of Texture and Microstructure by the Moving Detector Method
(
- Textures and Microstructures
, 2003)
In order to describe texture and microstructure of a polycrystalline material completely, crystal orientation g={?1F?2} must be known in all points x={x1?x2?x3} of the material. This can be achieved by locationresolved ...
Arsenic release from a natural rock under near-natural oxidizing conditions
(
- Engineering in life sciences
, 2008)
The solubilization of arsenic (As) from an ore material (native Arsenic [As, trig.] with Lollingite [FeAs2, rh.]) was characterized in leaching tests lasting for ≤ 99 days. The experiments were performed with materials of ...
Pedogenic carbonates as a proxy for palaeo-CO2 in the Palaeozoic atmosphere
(
- Elsevier
, 2006)
According to a model by Cerling (1991, 1999), the carbon isotope composition
of calcretes should depend on the soil type and the CO2-concentration in the atmosphere.
We have tested Cerling’s model by investigating 14 ...
Characterizing As, Cu, Fe and U solubilization by natural waters
(
- Springer-Verlag, Berlin/Heidelberg
- Springer, Berlin/Heidelberg
, 2008)
The effects of carbonate concentration and the presence of in-situ generated iron oxide and hydroxide phases (iron oxyhydroxides) on arsenic (As), copper (Cu), and uranium (U) release from natural rocks were investigated ...
On the Operating Mode of Bimetallic Systems for Environmental Remediation
(
- Journal of hazardous materials
, 2008)
Einschlüsse in Mineralen
(Deutscher Verlag für Grundstoffindustrie, Leipzig, 1987)
Das erste deutschsprachige Buch zur Einschlußforschung gibt einen geschlossenen Überblick über Geschichte, physikochemische Grundlagen, Einzelmethoden und Anwendungsmöglichkeiten der Untersuchung von Einschlüssen in ...
