目的对国产天然蒙脱石粘土的矿物组成和化学成分进行分析,探讨蒙脱石粘土作为药用的物质基础。方法应用X-射线衍射和X-射线荧光分析法对蒙脱石粘土样品中的矿物组成和化学成分进行定量分析。结果得到了6个蒙脱石粘土样品的基本矿物组成和化学成分。结论不同矿床的蒙脱石粘土的矿物组成有一定差异,但主矿物蒙脱石的含量平均为86%,且化学组成基本相似。

Object The mineralogical and chemical compositions of the natural pharmaceutical montmorilloniteclay 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 montmorilloniteclay 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 montmorilloniteclay samples from different deposits, the average percentage of montmorillonite content in samples is 86%, and the chemical composit ions of six samples are nearly similar.
