Research Interests

  • Arsenic-sulfur speciation with IC-ICP-MS
  • Structural characterization of thioarsenates and thioarsenites (X-ray absorption spectroscopy (XAS), ESRF, Grenoble, France, SSRL, Stanford, USA)
  • Abiotic formation of thioarsenates and thioarsenites under oxic and anoxic conditions (arsenite-sulfide mixes, leaching of As-S-minerals, leaching of sorbed arsenic species in sulfidic waters)
  • Microbial catalyzed formation of arsenic-sulfur species (bacterial strain: MLMS-1, species identification with IC-ICP-MS and XAS)
  • Thioarsenate stability in iron containing systems (stability: reaction with iron, effect of UV-irradiation, effect of solution matrix, oxic vs. anoxic conditions; preservation studies)
  • Mobilization and immobilization of thioarsenic species from/on iron(hydr)oxides mineral surfaces
  • Uptake of different arsenic species by model plant organism (A. thaliana)
  • Simple sorption/speciation modelling with PhreeqC
