A method for activation of bentonites is described. The method comprises a prior treatment of the bentonite with an organic polymer and/or an aqueous alkaline solution as known from prior art. Subsequently, an amount of 0.01 - 10% by weight from the treated bentonite of a heavy metal salt is incorporated into the pretreated bentonite and then dried at a temperature not higher than 400*C.

Bentonite belongs to the group of clays whose technical properties are controlled by the proportion of montmorillonite, a sub-group within the smectitic clays. It is clay derived from deposits of weathered volcanic ash. Bentonites are hydrated aluminosilicates, which composed predominantly of the clay mineral montmorillonite.
