| 摘 要： | 分别采用压片法与漫反射法测得几种不同产地高岭土的红外吸收谱图,解析了各高岭土的结构特征与吸收峰值的关系,发现利用漫反射傅里叶红外光谱技术,经K-M函数校正的红外谱图较压片法灵敏度高,也更准确,解析更简单;依据对高频区3700～3600cm-1波数段高岭石OH基特征吸收峰的吸收情况,可快速判断高岭石结晶度,结果与X射线衍射技术所测Hinckley指数(Hi)一致。

| Abstract: | Respectively using pressed method and diffuse reflectance method,the infrared absorption spectrua of sorts of kaolin in various areas were obtained.The relationship between the structure characteristics of kaolin and its absorption peaks was analyzed.The results showed that compared with pressed method,the use of diffuse reflectance Fourier transform infrared spectroscopy,combined with the K-M function,results in corrected infrared spectra with high sensitivity and is more accurate and easier to analyze.Fur... |
