Raman spectroscopy and its application in characterizing the structure of supersaturated sodium aluminate liquors

综述了拉曼光谱仪的发展历史、基本原理及其在过饱和铝酸钠溶液的结构表征领域中的应用.指出随着灵敏度、分辨率的提高,拉曼光谱仪将提供更多、更细的铝酸钠溶液微观结构信息并促使铝酸钠溶液结构表征从定性向半定量乃至定量发展;拉曼光谱仪与溶液X射线衍射仪、核磁共振、红外、紫外等光谱仪的联用,将更全面地表征铝酸钠溶液的微观结构;实现对工业铝酸钠溶液的结构分析及铝酸钠溶液的原位检测,是拉曼光谱仪表征过饱和铝酸钠溶液结构的必然发展方向.

Raman spectroscopyg development history,basic principle and its application in characterizing the structure of supersaturated sodium aluminate liquors were introduced. It is shown that the improvement of sensitivity and resolution of Raman spectroscopy will lead to more and finer structural information of sodium aluminate liquors, making the characterization of the structure of sodium aluminate liquors from qualitative to semi-quantitative,and even to quantitative. Raman spectroscopy can characterize the structure of sodium alumiante liquors better if it is combined with solution XRD, NMR, IR, UV or other spectrometers. To measure online and to measure industrial liquors are the development trends for Raman spectroscopy characterizing the structure of sodium aluminate liquors.
