Autor: Andrew N. Thomas, Elisabeth Eiche, Jörg Göttlicher, Ralph Steininger, Liane G. Benning, Helen M. Freeman, Dominique J. Tobler, Marco Mangayayam, Knud Dideriksen, Thomas Neumann
Publikováno v: Geochemical Transactions, Vol 21, Iss 1, Pp 1-16 (2020)
Abstract Chromium contamination is a serious environmental issue in areas affected by leather tanning and metal plating, and green rust sulfate has been tested extensively as a potential material for in situ chemical reduction of hexavalent chromium

A Combined X-ray Absorption and Mössbauer Spectroscopy Study on Fe Valence and Secondary Mineralogy in Granitoid Fracture Networks: Implications for Geological Disposal of Spent Nuclear Fuels
Autor: Mikael Tillberg, Henrik Drake, Zhaoliang Song, Steen Mørup, Mats E. Åström, Knud Dideriksen, Changxun Yu
Publikováno v: Environmental Science & Technology. 54:2832-2842
Underground repository in crystalline bedrock is a widely accepted solution for long-term disposal of spent nuclear fuels. During future deglaciations, meltwater will intrude via bedrock fractures to the depths of future repositories where O

Corrosion Rate Measurement and Oxide Investigation of AC Corrosion at Varying AC/DC Current Densities
Autor: Per Møller, Knud Dideriksen, Lars Vendelbo Nielsen, Andreas Junker Olesen
Publikováno v: CORROSION. 75:1026-1033
Corrosion of pipelines under cathodic protection (CP) caused by induced alternating current (AC) is highly dependent on the cathodic current density. This study uses electrical resistance probes to...

Publikováno v: Journal of Hazardous Materials
Mangayayam, M C, Perez, J P H, Alonso-de-Linaje, V, Dideriksen, K, Benning, L G & Tobler, D J 2022, ' Sulfidation extent of nanoscale zerovalent iron controls selectivity and reactivity with mixed chlorinated hydrocarbons in natural groundwater ', Journal of Hazardous Materials, vol. 431, 128534 . https://doi.org/10.1016/j.jhazmat.2022.128534
Sulfidated nanoscale zerovalent iron (S-nZVI) exhibits low anoxic oxidation and high reactivity towards many chlorinated hydrocarbons (CHCs). However, nothing is known about S-nZVI reactivity once exposed to complex CHC mixtures, a common feature of

A novel, direct-push approach for detecting sulfidated nanoparticulate zero valent iron (S-nZVI) in sediments using reactive and non-reactive fluorophores
Autor: Knud Dideriksen, Dominique J. Tobler, Klaus Weber, Markus Reischer, Anders G. Christensen
Publikováno v: Reischer, M, Christensen, A G, Weber, K, Tobler, D J & Dideriksen, K 2021, ' A novel, direct-push approach for detecting sulfidated nanoparticulate zero valent iron (S-nZVI) in sediments using reactive and non-reactive fluorophores ', Journal of Contaminant Hydrology, vol. 243, 103896 . https://doi.org/10.1016/j.jconhyd.2021.103896
Injection of microparticulate and nanoparticulate zero valent iron has become a regularly used method for groundwater remediation. Because of subsurface inhomogeneities, however, it is complicated to predict the ZVI transport in the subsurface, meani

Order and Disorder in Layered Double Hydroxides: Lessons Learned from the Green Rust Sulphate - Nikischerite Series
Autor: Knud Dideriksen, Laura Voigt, Marco Mangayayam, Simon H. J. Eiby, Case M. van Genuchten, Cathrine Frandsen, Kirsten M. Ø. Jensen, Susan Stipp, Dominique J. Tobler
Layered double hydroxides (LDHs) occur naturally and are synthesised for catalysis, drugdelivery and contaminant remediation. They consist of Me(II)-Me(III) hydroxide sheetsseparated by hydrated interlayers and weakly held anions. Often, LDHs are nan

Direct Visualization of Arsenic Binding on Green Rust Sulfate
Autor: Jeffrey Paulo, H Perez, Helen M, Freeman, Andy P, Brown, Case M, van Genuchten, Knud, Dideriksen, Mark, S'ari, Dominique J, Tobler, Liane G, Benning
Publikováno v: Environmental sciencetechnology. 54(6)
"Green rust" (GR), a redox-active Fe(II)-Fe(III) layered double hydroxide, is a potential environmentally relevant mineral substrate for arsenic (As) sequestration in reduced, subsurface environments. GR phases have high As uptake capacities at circu
