- Abstract
- A series of sodium bentonites as raw material were purified. The purification bentonite was used to prepare clay nanocomposite with the requirement of high montmorillonite content. The methylene blue absorbed and swelling volume were selected as two indexes. And the optimal purification conditions were measured: bentonite slurry concentration of 7%, stirring time of 20min, centrifugal time of 30min, none dispersant agent requested. Then the montmorillonite content reached as high as 98.66%. The grain size, structural characterization and morphology of the purification bentonites were observed by means of X-ray diffraction, scanning electron microscopy. A better dispersibility and higher content matrix of montmorillonite were obtained by the purification process of bentonite.
