硫代硫酸钠、硫酸钠和亚硫酸钠化学结构相似，为了对硫酸盐分子结构有更深层次的了解，本文采用中红外（MIR）光谱（包括一维 MIR 光谱、二阶导数 MIR 光谱、四阶导数MIR 光谱和去卷积 MIR 光谱）开展了硫酸盐分子（包括硫代硫酸钠、硫酸钠和亚硫酸钠）的结构研究。实验发现，硫酸盐分子的中红外吸收模式主要包括ν■、ν■、δ■、ν■、β■。本项研究同时开展对硫代硫酸钠、硫酸钠和亚硫酸钠进行 MIR 光谱分析的研究，拓展了 MIR 光谱在硫酸工业领域的研究范围。
The chemical structure of sodium thiosulfate, sodium sulphate and sodium sulfite are similar. In order to have a deeper understanding of the molecular structure of sulfate, mid infrared (MIR) spectra (including one-dimensional MIR spectra, second derivative MIR spectra, fourth derivative MIR spectra and deconvolution MIR spectra) are used to study sulfate molecules (including sodium thiosulfate Study on the structure of sodium sulfate and sodium sulfite).The middle infrared spectroscopy absorption mode of sulphate molecular mainly included νasSO4-sulfate molecule,νsSO4-sulfate molecule,δasSO4-sulfate molecule,νasSO3-sulfate molecule,βSO3-sulfate molecule.In this study, the MIR spectrum analysis of sodium thiosulfate, sodium sulfate and sodium sulfite was carried out at the same time, which expanded the research scope of MIR spectrum in the field of sulfuric acid industry.
