Abstract

Reference samples of kaolinite KGa-1b and montmorillonite STx-1b have been studied by infrared spectroscopy at different humidity. The spectral features reflecting the formation of water layers on the basal surfaces of individual minerals have been studied. The experimental studies have been performed using infrared spectroscopy of disturbed total internal reflection. The composition of wet samples has been analyzed by decomposing the experimental spectra into the spectrum of H₂O and used minerals in the air-dry state. The obtained dependences of the coefficients of participation of the basic spectra on humidity have been compared with the results of the measurements in the ultrahigh frequency range and they allow us to study the integral features of the formation of a water layer on mineral particles and to evaluate the plastic characteristics of clays. The anomalous position of the maximum and the half-width of the band of valence vibrations of water at low humidity have been found.

红外光谱研究蒙脱土和高岭土表面水膜的形成特征

摘要

高岭石KGa-1b和蒙脱石STx-1b的参考样品已通过红外光谱法在不同湿度下进行了研究。已经研究了反映单个矿物基础表面上水层形成的光谱特征。已经使用红外光谱对受扰的全内反射进行了实验研究。通过将实验光谱分解为H ₂的光谱来分析湿样品的成分O和用过的矿物质处于风干状态。已将获得的基本光谱的参与系数对湿度的依赖性与超高频范围内的测量结果进行了比较，它们使我们能够研究矿物颗粒上水层形成的整体特征并进行评估粘土的塑性特征。发现了低湿度下水的价态振动带的最大值和一半宽度的反常位置。
