改性硅藻土的表征研究

Research of the Modified Diatomite by SEM, XRD and FTIR Methods

通过酸洗、钠化等工艺分别对天然硅藻土进行改性,并采用扫面电子显微镜SEM\X射线衍射分析仪、傅立叶红外光谱分析仪对改性硅藻土的表面性能和分子结构进行研究,了解酸洗、钠化改性工艺对天然硅藻土的改性机理。

Modified diatomite was prepared by acid and sodium modification. X-ray diffraction analysis. Fourier transform infi＇ared spectroscopy, Scanning electron microscope were applied to study the microstructure and phase constitution of modified diatomite.
