摘要
本文对广东和平蒙脱石及其酸处理产物进行了化学分析、X射线粉末衍射分析、红外吸收光谱分析、电子顺磁共振谱、原子力显微镜及魔角旋转核磁共振等研究．结果表明，酸处理浓度对蒙脱石的表面结构有很大的影响．当酸处理浓度达到20％时，蒙脱石的Q3Si结构有部分转变为畸变的Q3Si结构和Q4Si结构，而Al的结构状态则没有发生任何变化，这与原子力显微镜的观察结果相一致．
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.
