摘要
通过对来自不同产地、不同矿层的十个蒙脱石样品进行提纯和钠化处理,研究了它们的水化能和红外光谱(IR),发现所测样品光谱的 I_(520cm)/I_(1035cm)值和 I_((910cm)^(-1))/I_((1035cm)^(-1))值与膨润量有较好的相关性。从而提出评价蒙脱石水化性能的红外光谱法。
The hydratability and IR spectra of the montmorillonites from different localities and strata were determined after the clay were separated from associated minerals and converted to the Na-saturated. The degree of swelling showed a corelation with intensity of the IR absorption band.The infrared spectra method for judgement on the hydratability of montmorillonites were put forward.
