Microstructure of Montmorillonite and Its Acid Treatment Products
|
Abstract:
The montmorillonite in Heping, Guangdong province was studied by chemical analysis,XRD, IR, EPR, AFM and MAS NMR. It was found that acid treatmellt is influential on the surface of montmorillonite. When the concentration of acid reaches 20%, some Q3 Si structure in montmorillonite is transformed to distortional Q3 Si structure and Q4 Si structure, and there is no any change about Al structure state in montmorillonite, that is in line with the observational result of atomic force microscope very well.
