Surface properties of smectites fine fractions as precursors of multifunctional composites
Popis výsledku v původním jazyce
The study focuses on evaluating surface properties of raw and activated smectites fine fractions in relation to their potentialities as precursors for multifunctional composites. Mineral standard samples of four montmorillonites as representatives of the smectite mineral group were purified and chemically activated. Both the starting materials and the activated samples were characterized by X-ray diffraction analysis (XRD), changes in the surface and pore properties were studied by low nitrogen adsorption method and surface morphology by scanning electron microscope (SEM). On the basis of obtained results it can be concluded that activated materials exhibit changes of structural and surface properties. The modification mainly affected meso-macroporous montmorillonite samples. In these cases, the prepared samples are potentially suited to be precursors of multifunctional sorbents with enhanced sorption properties.
