| 摘 要： | 通过对徐闻、三水、高州等地五个样品的Ｘ射线衍射分析，化学全分析，分析它们为含铁量不同的蒙脱石，层间可交换阳离子主要为Ｃａ＾２＋。几个样品穆斯堡尔谱表明铁主要以Ｆｅ＾３＋的形式存在，含铁量较高的样品ＸＧＡ、ＸＳＡ、ＳＳ的谱可以拟合出Ｆｅ＾３＋的二对四级双峰，表明铁在蒙脱石中占据两种不等同的八面体位置。

| Abstract: | Five montmorillonite samples have been studied by chemical analysis, XRD and Mossbauer spectra of Cpx mssbauer spectroscopy. It is found that they have various iron contents. The57Fe Mossbauer spectra of Cpx mssbauer spectra of the three montmorillonites high in Fe content. were computer-fitted with two Fe3+ doublets, showing that iron principally exists in the formof Fe3+ and Fe3+ is present in two different octahedral sites. |
