Abstract

Montmorillonite plays an important role in mineral research, pharmaceutical research and treatment of polluted wastewater. The purpose of this study is to detect different porosity, thickness, calcined products of montmorillonite and to distinguish different types of montmorillonite by terahertz time-domain spectroscopy combining with other conventional analytical methods. In addition, optical parameters such as absorption coefficient, phase difference and refractive index can significantly characterize different porosity, thickness and calcination temperature. Therefore, it is of great significance to use terahertz time-domain spectroscopy for nondestructive testing of montmorillonite.
