Charakterizace strukturních vlastností nanovermikulitů po acidifikaci

Abstract

This thesis is focused on the preparation and characterization of acidificated nanovermiculites from different areas – Bulgaria and Brazil. Characterization of phyllosilicate structure considering vermiculite and his acdification are discussed in theoretical part. The practical part of thesis aimed with the acidification of vermiculites with different concentration of hydrochloric acid. The structural properties of the nanovermiculites before and after acidification were determined based on the elemental analysis, measurement of specific surface area, determination of cation exchange capacity, X-ray diffraction analysis, infrared spectroscopy, analysis of particle size distribution and scanning electron microscopy.
