• Clinoptilolite-rich tuff
• Montmorillonite-rich bentonite
• Fe-oxihydroxide GEH
• Adsorption

Commercial Fe-oxihydroxide (GEH) and clinoptilolite-rich tuff proved to have a quite low aluminum uptake in current research, however montmorillonite-rich bentonite's maximum capacity towards aluminum was approximately 4-times higher. Also, the best chromate adsorption was observed on montmorillonite-rich bentonite. Concerning halides uptake on octadecylammonium (ODA)-modified zeolite, large and therefore less hydrated anions with better fitting energetic configurations, as e.g. iodide, were on ODA-clinoptilolite-rich tuff preferred. Chemically pretreated FeO(OH) clinoptilolite-rich tuff with the GEH product showed identical performance towards Sb-species.
