Experiments were carried out to investigate the role of the different soil minerals for adsorption, fixation, and remobilization of automobile catalyst emitted platinum group elements – PGE (Pt, Pd, Rh). It was shown that the adsorption capacity of the investigated soil minerals (kaolinite, Mn/Feoxides, quartz, feldspar, calcite) shows large differences mainly depending on specific surface and surface loading. The pH value plays an important role for the buffer capacity of calcite. Kaolinite and Mn/Fe-oxides are characterized by high-specific surface and variable surface loading, expressing the highest adsorption capacity and also stronger bonding for the PGE.
Individual PGE show differences in respect of their adsorption behaviour. Platinum was adsorbed slower and to a much lower extend than Pd and Rh. Pd is the most easily removable element, even though it was adsorbed to a relatively high amount by all investigated minerals.
The experiments demonstrated that mineralogical composition and geochemical conditions of soil exert a decisive influence on fixation and remobilization of catalyst emitted PGE.
