In this work, the authors attempt to interpret the visible, infrared and Raman spectra of ferrate(VI) by means of theoretical physical-inorganic chemistry and historical highlights in this field of interest. In addition, the sacrificial decomposition of ferrate(VI) during water treatment will also be discussed together with a brief mention of how Rayleigh scattering caused by the decomposition of FeO may render absorbance readings erroneous. This work is not a compendium of all the instrumental methods of analysis which have been deployed to identify ferrate(VI) or to study its plethora of reactions, but mention will be made of the relevant techniques (e.g., Mössbauer Spectroscopy amongst others) which support and advance this overall discourse at appropriate junctures, without undue elaboration on the foundational physics of these techniques.
在这项工作中，作者试图通过理论物理无机化学和该领域的历史亮点来解释高铁酸盐（VI）的可见、红外和拉曼光谱。此外，还将讨论高铁酸盐（VI）在水处理过程中的牺牲分解，以及简要提及由于 FeO 的分解引起的瑞利散射如何使吸光度读数出现误差。这项工作并不是所有已部署用于鉴定高铁酸盐（VI）或研究其众多反应的仪器分析方法的汇编，但将提及支持和推进这一整体论述的相关技术（例如穆斯堡尔光谱学等），而不会在这些技术的基础物理学上过度阐述。
