Abstract

An adsorbent is described based on an inorganic support material with exchangeable mono- and divalent cations, characterized by the fact that the specific surface of the support material is >100 m.sup.2 /g, its cation exchange capacity is>30 mg-equiv/100 g, its pore volume is>0.15 m/g, the pH value of an aqueous suspension of 8 g of support material in 100 mL of H.sub.2 O is<7.5 and that at least 60, preferably at least 70% of the exchangeable mono- and/or divalent cations are exchanged by cations acting as Lewis acids, preferably Al.sup.3 + cations.
