Özet:

 

It was determined by X-ray diffraction that, besides containing clay  minerals such as montmorillonite and illite, the original bentonite  contained also clinoptilolite, opal-C, quartz, calcite and dolomite.   The original bentonite was separated into four fractions by  decantation and precipitation from its aqueous suspension.  The  adsorption and desorption of nitrogen on the original bentonite and  its fractions at 77 K were investigated.  The specific surface areas  of the samples were determined according to the methods of Brunauer-Emmett-Teller, de Boer-Lippens, and Harkins-Jura by using the adsorption data.   The mesopore size distribution curves were plotted by using the  desorption data.  The specific micropore and the specific  micropore-mesopore volumes were determined by the extrapolation of  these curves.  The correlation between the specific surface areas and  the specific micropore-mesopore volumes is discussed.
