1.Thermodynamic modelling of the speciation of metals with Dissolved Organic Matter (such as Humic and Fulvic Acids). We describe the specific binding between organic matter and metal ions with stepwise binding constants or with the Conditional Affinity Spectrum (concept introduced by our group).
2.Dynamic aspects of metal and nanoparticles behaviour.This includes the quantitative description of the relationship between reaction and diffusion, using tools such as the lability degree (introduced by the group). Other studied dynamic systems are dissolution, aggregation and settling of nanoparticles and the modelling of bioavailability and biouptake.
3.Emerging analytical techniques for metal speciation. We designed and and keep developing the technique AGNES (Absence of Gradients and Nernstian Equilibrium Stripping) for a direct measurement of free metal ion concentrations. We are also working with DMT (Donnan Membrane Technique) and DGT (Diffusion Gradients in Thin Films), as complementary techniques to provide information on the target system.
