Metallic iron for environmental remediation: learning from electrocoagulation.
The interpretation of processes yielding aqueous contaminant removal in the presence of elemental iron (e.g. in Fe(0)/H(2)O systems) is subject to numerous complications. Reductive transformations by Fe(0) and its primary ...
Exploring the influence of operational parameters on the reactivity of elemental iron materials.
In an attempt to characterize material intrinsic reactivity, iron dissolution from elemental iron materials (Fe(0)) was investigated under various experimental conditions in batch tests. Dissolution experiments were performed ...
On the mechanism of microbe inactivation by metallic iron
This letter challenges the concept that the metallic iron (Fe0) surface contributes directly to the process of micro-organism inactivation in aqueous solutions. It is shown that any antimicrobial properties of Fe0 is related ...
Enhancing the Sustainability of Household Fe0/Sand Filters by Using Bimetallics and MnO2
Filtration systems containing metallic iron as reactive medium (Fe0 beds) have been intensively used for water treatment during the last two decades. The sustainability of Fe0 beds is severely confined by two major factors: ...
Geochemistry of natural wetlands in former uranium milling sites (eastern Germany) and implications for uranium retention
Discharge from former uranium mining and milling areas is world wide a source of elevated uranium contents in wetlands. The efficiency of organic rich wetland environments for entrapment and accumulation of uranium was ...
Characterizing the discoloration of methylene blue in Fe0/H2O systems.
Methylene blue (MB) was used as a model molecule to characterize the aqueous reactivity of metallic iron in Fe(0)/H(2)O systems. Likely discoloration mechanisms under used experimental conditions are: (i) adsorption onto ...
Characterizing the effects of shaking intensity on the kinetics of metallic iron dissolution in EDTA.
Despite two decades of intensive laboratory investigations, several aspects of contaminant removal from aqueous solutions by elemental iron materials (e.g., in Fe(0)/H2O systems) are not really understood. One of the main ...
