A critical review on the process of contaminant removal in Fe0-H2O systems.
A central aspect of the contaminant removal by elemental iron materials (Fe0 or Fe0 materials) is that reduction reactions are mediated by the iron surface (direct reduction). This premise was introduced by the pioneers ... -
An analysis of the evolution of reactive species in Fe0/H2O systems.
Aqueous contaminant removal in the presence of metallic iron (e.g. in Fe(0)/H(2)O systems) is characterized by the large diversity of removing agents. This paper analyses the synergistic effect of adsorption, co-precipitation ... -
Aqueous contaminant removal by metallic iron: Is the paradigm shifting?
Chemical reduction has long dominated the thinking about the mechanism of aqueous contaminant removal in the presence of metallic iron (e.g. Fe0/H2O systems). However, a large body of experimental evidence indicates that ... -
Arsenic Release from a Natural Rock under Near-natural Oxidizing Conditions
The effects of carbonate concentration and the presence of iron hydroxide phases on the process of arsenic release from an ore material were investigated under experimental oxic conditions and in the pH range from 6.0 to ... -
Characterising the reactivity of metallic iron in Fe0/As-rock/H2O systems by long-term column experiments
The intrinsic reactivity of four metallic iron materials (Fe0) was investigated in batch and column experiments. The Fe0 reactivity was characterized by the extent of aqueous fixation of in-situ leached arsenic (As). ... -
Characterizing As, Cu, Fe and U solubilization by natural waters
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 ... -
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 ... -
Characterizing the reactivity of metallic iron in Fe0/EDTA/H2O systems with column experiments
Characterizing the intrinsic reactivity of iron materials for environmental remediation has received relative little interest. Available results are mostly based on the removal extent of selected contaminants in batch ... -
Characterizing the reactivity of metallic iron in Fe0/UVI/H2O systems by long-term column experiments
Aqueous iron corrosion has been identified as a powerful process for environmental remediation and safe drinking water provision. The intrinsic reactivity of conventional micro-scale metallic iron (Fe0) has been mostly ... -
Characterizing the reactivity of metallic iron upon methylene blue discoloration in Fe0/MnO2/H2O systems.
A simple method is proposed for testing the reactivity of elemental iron materials (Fe(0) materials) using methylene blue (MB) as reagent. The method is based on the oxidative reactivity of Fe(II) for reductive dissolution ... -
Comment on "Reductive dechlorination of gamma-hexachloro-cyclohexane using Fe-Pd bimetallic nanoparticles" by Nagpal et al. [J. Hazard. Mater. 175 (2010) 680-687].
The author used a recent article on lindane reductive dechlorination by Fe/Pd bimetallics to complain that dozen of published works in several journals are not conform to the state-of-the-art knowledge on the mechanism of ...
