Research Interest

Development and application of radiotracers to gain advanced understanding of processes determining contaminant transport mediated by macromolecular organic complexants


Ongoing Projects

  • Geochemical retention of radionuclides at cement alteration phases – influence of polymeric cement additives: radiotracer studies on complexation and (co-)adsorption of radionuclides with polycarboxylate ethers (superplasticisers) at hyperalkaline conditions and high salinity; modelling the effects of pH and electrolyte content on the basis of interactions in the constituent subsystems (BMWi project, in cooperation with the division "Surface Processes") [Description]

Completed Projects (1995 - 2015)

  • Geochemical behaviour and transport of radionuclides in saline systems with organic matter relevant to a final repository site: influence of high salinity (NaCl, MgCl2, CaCl2) on the mobilising potential of humic-like clay organics towards radionuclides at variable pH; modelling metal-fulvate complexation by the NICA-Donnan approach; isotope exchange studies on the dynamics of metal-humate complexation equilibria depending on concentration and time of contact (BMWi project, in cooperation with the division "Surface Processes") [Article 1] [Article 2]
  • Elementary processes relevant to humic-bound actinide transport in potential host rock formations of a final repository: effect of humic substances and carboxylic acids on the pH-dependent adsorption of radionuclides onto clay minerals; radiotracer studies on reversibility and equilibrium characteristics of adsorption of humic substances (BMWi project) [Article 1] [Article 2]
  • Humic-bound transport of toxic metals and polycyclic aromatic hydrocarbons (PAH) at a contaminated site in Staßfurt (Saxony-Anhalt, Germany): sampling and analytics along the groundwater flow path; humic-bound solubilisation and adsorption of PAH depending on pH and ionic strength; properties and solubilising potential of mixed aggregates of humic substances and surfactants (BMBF project) [Article 1] [Article 2]
  • Formation and partitioning of humate species of mobilised radiotoxic metals in geochemical systems: competition effects of Al(III) and Fe(III) on humate complexation of radionuclides; elucidation of long-term kinetic processes (BMWA project) [Article 1] [Article 2]
  • Competitive reactions of trivalent metals with respect to complexation and co-adsorption of radionuclides with humic acids: combined Kd model of metal mobility in geochemical systems with humic matter; influence of pH and competing metals; relating complex stability and flocculation (BMWi project) [Article 1] [Article 2]
  • Interaction of phenol with dissolved and adsorbed surfactant aggregates: qualitative and quantitative characterisation of mixed aggregates and phase behaviour; modelling surfactant adsorption (PhD thesis, University of Leipzig) [Article 1] [Article 2]
