Thermodynamic modelling of metal ion speciation with Dissolved Organic Matter (DOM) with tools such as stepwise binding constants or the Conditional Affinity Spectrum (CAS). Electrostatic binding
Dynamic aspects of metal and nanoparticles behaviour such as the lability degree (comparing reaction/diffusion rates), dissolution, aggregation and settling of nanoparticles and bioavailability and biouptake modelling.
Analytical techniques for experimental metal speciation such as DMT (Donnan Membrane Technique), DGT (Diffusion Gradients in Thin Films) and AGNES
Instrumentation:
Absence of Gradients and Nernstian Equilibrium Stripping (AGNES) is an electroanalytical technique (designed and developed by us) able to measure free metal ion concentrations for certain elements (Zn, Cd, Pb, Cu, Sn, In, Ga, Tl, etc.) in aqueous (or hydroalcoholic) solutions.
Donnan Membrane Technique (DMT) allows finding the free metal ion concentration of many cations at the same time.
Diffusion Gradients in Thin Films (DGT) allows measuring the "labile" fraction of metal ions in waters and soils
