鸟粪石分析与表征技术综述

The Review of The Analysis and Characterization Technologies for Struvite

对X射线衍射(XRD)、傅里叶红外光谱(FT-IR)和拉曼光谱(Raman)、热分析(TGA)及化学分析法等技术用于分析和表征鸟粪石的最新研究进展进行了综述。表明X射线衍射、傅里叶红外光谱和拉曼光谱等能定性判断所得沉淀中是否含有鸟粪石,而难以定量分析鸟粪石含量。通过元素分析以及由此而建立的鸟粪石含量计算方法可以定量确定沉淀中鸟粪石的含量。热分析能提供热性能信息从而为所得沉淀的干燥处理过程提供有用的依据。

The analysis and characterization technologies for struvite, including X - ray diffraction, FT - IR and FT - Raman spectra, thermal analysis, and chemical analysis were reviewed. X - ray diffraction and FT - IR and FT - Raman spectra can qualitatively determine the presence of struvite in the precipitates. The element analysis （EA） and the calculation method based on EA can quantitatively define the exact content of struvite. The thermal property obtained from TGA can provide valuable information to the dry treatment of the precipitates.
