On the Operating Mode of Bimetallic Systems for Environmental Remediation
(Journal of hazardous materials, 2008) -
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 ... -
Predictive modeling of organic pollutant leaching and transport behavior at the lysimeter and field scales
(Univ. Dresden, 2007)Soil and groundwater pollution has become a global issue since the advent of industrialization and mechanized agriculture. Some contaminants such as PAHs may persist in the subsurface for decades and centuries. In a bid ... -
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: ... -
Sorption von Metallen und Halbmetallen im bergbaulich beeinflußten Feuchtgebiet Lengenfeld / Vogtland
(Freiberg Online Geosciences; Vol. 08.2002) -
Testing the Suitability of Zerovalent Iron Materials for Reactive Walls
(Environmental Chemistry, 2004)Zerovalent iron (ZVI) has been proposed as reactive material in permeable in situ walls for contaminated groundwater. An economically feasible ZVI-based reactive wall requires cheap but efficient iron materials. From an ... -
Uranium release from a natural rock under near-natural oxidizing conditions
(Journal of radioanalytical and nuclear chemistry, 2006)Understanding how uranium (U) moves through the soil and groundwater is essential to determine the effectiveness of cleanup technologies. Uranium release and transport in the subsurface under oxic conditions have been ...
