Presentation

I am interested in the speciation of metal(loids)s in the environment, both in surface water and in soils, but also in bottom ashes. I am specialized in the techniques EXAFS spectroscopy, geochemical modelling, and µ-XRF, but I have also used other techniques such as PCCS, cross-flow ultrafiltration, dialysis, SEM, AAS, ion-selective electrode. Metal(loid)s I have studied are Al, As, Cr, Cu, Fe, Mo, Pb, Sb, Si and Zn.
