Abstract:
Object The mineralogical and chemical compositions of the natural pharmaceutical montmorillonite clay were analysed with the aim of approaching the material base of its action Methods The means of X ray diffraction (SRD) and X ray fluorescence (SRF) were used for the quantitative analysis of the mineralogical and chemical compositions of the montmorillonite clay samples Results The essential mineralogical and chemical compositions of the six samples were obtained Conclusion Though there is some difference in mineralogical composition of the montmorillonite clay samples from different deposits, the average percentage of montmorillonite content in samples is 86%, and the chemical compositions of six samples are nearly similar
