An analysis of the evolution of reactive species in Fe0/H2O systems.
(Journal of hazardous materials, 2009-09-15)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 ... -
Characterizing the effects of shaking intensity on the kinetics of metallic iron dissolution in EDTA.
(Journal of hazardous materials, 2009-10-30)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 upon methylene blue discoloration in Fe0/MnO2/H2O systems.
(Journal of hazardous materials, 2009-09-15)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 ... -
Comments on: “Comparison of reductive dechlorination of p-chlorophenol using Fe and nanosized Fe00.” By R. Cheng et al. J. Hazard. Mater. 144 (2007) 334.

Elemental metals for environmental remediation: learning from cementation process.
(Journal of hazardous materials, 2010-09-15)The further development of Fe(0)-based remediation technology depends on the profound understanding of the mechanisms involved in the process of aqueous contaminant removal. The view that adsorption and co-precipitation ... -
Characterizing the discoloration of methylene blue in Fe0/H2O systems.
(Journal of hazardous materials, 2009)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 ... -
Exhumation history and landscape evolution of the Sierra de San Luis (Sierras Pampeanas, Argentina) - new insights from low - temperature thermochronological data
(Andean Geology, 2017)This paper presents low-temperature thermochronological data and K‑Ar fault gouge ages from the Sierra de San Luis in the Eastern Sierras Pampeanas in order to constrain its low-temperature thermal evolution and ... -
Trachyte weathering in the urban built environment related to air quality
(Heritage Science, 2017)Decay of trachyte used as building stone in urban environment was investigated through the analysis of crusts and patinas found on trachyte of the Euganean Hills in the Renaissance city walls of Padua, northeastern Italy. ... -
Snowmobile impacts on snowpack physical and mechanical properties
(The Cryosphere, 2018)Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different ... -
Climate effects on vegetation vitality at the treeline of boreal forests of Mongolia
(Biogeosciences, 2018)In northern Mongolia, at the southern boundary of the Siberian boreal forest belt, the distribution of steppe and forest is generally linked to climate and topography, making this region highly sensitive to climate change ... -
