purification has become a topic of research. In this study, the use of bentonite clay modified by acid activation is proposed. Sulfuric acid, acetic acid (v-acid/w-clay ratio=20, 40 and 60%) and sulfuric/acetic mixtures (1:1 ratio) were used in the bentonite clay activation. The activated clays were used in the UMO

In view of the above it can be concluded that sorptive clays produced from bentonites by acid activation develop different adsorption capacities depending on the acid concentration. This is caused by a more or less strong acid attack primarily leaching out Al- and Fe-ions from the octahedron montmorillonite layers.

In the activation process of the sepiolite by acid treatment, dissolution of the Mg 2+ cations from structure takes place and then sepiolite transform into amorphous fibrous silica. The loss of octahedral cations due to acid treatment produces new acid cites in the clay structure, thus increasing the specific surface area and porosity.
