Hydrology und Experimental Biogeochemistry

Research interests:

  • Redox cycling of iron and sulfur and their impact on element mobility (Sb, As and Cr)
  • Interactions between metal(loid)s and mineral surfaces (e.g. iron hydroxides and iron sulfides)
  • Speciation and mobility of toxic metal(loids) in contaminated soils and sediments
  • Speciation and behaviour of toxic metal(loids) in synthetic products, e.g. Sb migration from baby clothes into body liquids
  • Methods: XAS (S, Fe, Sb, As and Cr), HPLC-ICP-MS, SEM-EDX, Laser ablation ICP-MS
