二氧化碳—水体系的拉曼光谱研究

Study on Raman Spectra of CO2-H2O System

摘要: 研究了使用石英管熔融封闭法分别在酸性、中性以及碱性条件下，采用ＣａＣＯ３或Ｎａ２ＣＯ３与ＨＣｌ反应制备不同浓度的ＣＯ２标准系列，并对气相、液相中的ＣＯ２进行拉曼光谱研究，得出了定量分析气相ＣＯ２所遵循的规律，即ＣＯ２的浓度与拉曼位移（１３８８．９ｃｍ－１）强度呈线性相关，为定量分析流体包裹体中ＣＯ２的含量奠定了基础。

Abstract: A series of CO 2 standards for Raman spectrometric microprobe analysis were prepared by reaction of CaCO 3 or Na 2CO 3 with HCl in acidic, basic and neutral solutions respectively in a sealed quartz tube. With these standards, the study on Raman spect
