作者根据高岭石类粘土矿物的红外光谱特征吸收和高频区OH基吸收强度的差异,对高岭石类粘上矿物进行了定性、定量分析。与X射线衍射法相比,红外吸收光谱法不但分析快速准确,而且可以消除绿泥石的干扰,同时特别适合于低含量样品的分析。

Based on the characteristics absorption of Infrared spectra and the Intensity differences of absorption for OH groups in high frequency range, qualitative and quantitative analysis for clay minerals of kaollnites were made. It is thought the method of Infrared absorption spectra is more time-saving and more accurate, as comparing with X-ray diffraction. Furthermore, the interference from chlorite can be eliminated. It is particularly appliable to the samples of low content (10%minor).
