Molecular modelling of natural and intercalated montmorillonites adsorbing phenole and aniline

Popis výsledku v původním jazyce

Montmorillonites (MMT) due to their enormous surface area and extendable interlayer space can be used as effective adsorbents for various organic substances. The properties of intercalated forms of MMT could be widely modified (originally hydrophilic surface turns into hydrophobic after sorption of organic compounds). The adsorption of phenol and aniline, which belong to hazardous pollutants occurring in effluents, was studied. Three intercalated samples were prepared and together with the sample of pure MMT were used as adsorbents. Modified montmorillonites were prepared by the intercalation and the sorption of three quaternary ammonium salts (cetyltrimethylammonium bromide, tetramethylammonium chloride and tetrabutylammonium iodide) into the interlayer space and on the surface of montmorillonite. The experimental results (adsorption curves, X-ray diffraction) revealed that intercalated montmorillonites adsorbed phenol much more readily than the pure sample (even though phenol was app
