Bentonite is cheap, natural raw material, whose usage is not detrimental to the environment. Bentonite clay is primarily composed of of smectite minerals, usually montmorillonite. Bentonite can be easily modified. Some of these modifications include pillaring and organomodification. Pillared clays (PILC) with incorporated mixed Al–Fe oxide pillars were used as Fenton-like catalysts in the catalytic oxidation of organic water pollutants in the presence of H2O2. The intercalation of quaternary alkyl ammonium cations resulted in the obtainment of organobentonites as adsorbents for the simultaneous removal of organic and inorganic pollutants. These sorbents are useful in the purification of multicomponent dye/toxic metal solutions and real waste waters. Organobentonites and PILCs were used as electrode materials in electroanalytic sensors and biosensors in environmental protection. Bentonite modification led to the synthesis of adsorbents for the removal of organic and toxic an...d radioactive inorganic pollutants, catalysts for the oxidation of water pollutants, sensors and biosensors, electrocatalysts.
