【摘要】 对7个不同产地的蒙脱石样品提纯钠化后由化学分析得到它们的化学结构式。用红外吸收光谱（IR）和电子自旋共振（ESR）方法对这7个具有不同四面体和八面体内阳离子类质同象置换量蒙脱石样品进行了研究。IR吸收谱中R—OH振动和R—O—Si振动吸收带均随置换情况不同而变化。ESR谱表明Fe³⁺离子在蒙脱石中有不同对称性的位置,并由于类质同象置换的不同,共振信号也有一定的变化。更多还原

【Abstract】 Seven montmorillonite samples from different localities were investigated by IR and ESR techniques have been separated from the associated minerals and conversed to Na-saturated samples. The influence of tetrahedral and octahedral replacement on the IR and ESR spectra of montmorillonites is discussed in the present paper.更多还原
