摘要
蒙脱石八面体层中(Fe^(3+)+Mg^(2+))含量影响晶胞参数b_0亦影响蒙脱石的比亲水性,即影响蒙脱石结合水膜的厚度。结合水膜厚度的大小,影响蒙脱石层间交换性阳离子在蒙脱石-水体系中的电导。本工作通过对不同地区,不同类型蒙脱石-水体系电导测试,讨论了蒙脱石八面体层中(Fe^(3+)+Mg^(2+))含量和晶胞参数b_0的变化对电导率影响的规律。
(Fe^(3+)+Mg^(2+)) content in octahedron of montmorillonite influences parameter b_0 and waer affinity of montmorillonite, i.e. thickness of binding water film. The thickness of water film infiuences the specific conductivity of exchangeable cations in the interlayer of montmorillonite in the montmorillonite-water system. In this study, the specific conductivity is determined for different districts and exchangeable cations in the interlayer of montmorillonite in the montmorillonite-water system, and the effect of the change of (Fos^(3+)+Mg^(2+)) content and cell parameter b_0 of montmorillonite on the specific conductivity is discussed.
