高温高压下电解质溶液谱学研究的进展

高温高压下电解质溶液研究在理论和工业应用上都具有重要的意义，拉曼光谱、红外光谱、紫外可见光谱、中子和X射线衍射、以及X射线吸收精细结构方法都已经用于它的研究。随着温度升高，溶液的结构发生了变化，离子的缔合度增加，内层配位水的数目减少，出现了离子的多核簇组成。除了静态结构的研究外，也用拉曼光谱进行溶液的动力学探讨。水热金刚石压腔装置是高温高压电解质溶液研究的一个重要的进步，在水热金刚石压腔装置中，拉曼光谱和X射线吸收精细结构两种方法具有重要的应用潜力。

The Progress on the Spectroscopy Study of Electrolyte Aqueous at High Temperature and High Pressure

The study of electrolyte aqueous at high temperature and high pressure is important in theory and industrial applications. The Raman, IR, UV\|Vis, neutron and X\|ray diffraction, and X\|ray absorption fine structure have been used to study the structure of electrolyte aqueous at high temperature and high pressure. With the increasing of temperature, the degree of ion associate increases, the number of water nearest the ion decreases, and the multinuclear ions structure appears. The dynamics is studied by Raman spectroscopy. The hydrothermal diamond anvil cell is the important progress, with Raman and X\|ray absorption fine structure, it has great potential application in the electrolyte aqueous at high temperature and high pressure.
