The influence of mechanical treatment of vermiculite on preparation of the composites vermiculite/TiO2
Popis výsledku v původním jazyce
The paper deals with the structure, properties and influence of mechanical treatment of raw vermiculite (VE) on subsequent preparation of vermiculite/TiO2 composites (VETI). Different mills, planetary ball-mill, vertical jet and cryogenic mills were usedfor the preparation of different particle size fractions of VE. Obtained VE fractions were modified by hydrolysis of titanyl sulfate (TiOSO4), whereas in this way, VETI composites with different content of TiO2 were prepared. Photocatalytic activity ofthese composites was determined by degradation of organic dye Acid Orange 7 (AO7) after exposure to UV light. This method is based on comparison of dye concentration in the aqueous phase before and after irradiation. Chemical composition of VETI composites was determined by X-ray fluorescence spectroscopy (XRFS). All of the fractions of the pure VE after the milling were characterized by the measurement of their particle size distribution. Structural properties were studied by X-ray powd
