摘要：

采用原位透射式傅里叶变换红外(FT-IR)光谱仪在线研究了UF₄/KBr在空气中室温条件下的水解反应及其热转化行为,获取反应前后不同铀化合物的红外光谱变化图.结果表明, UF₄/KBr在空气中的水解反应,首先主要生成的是UO₂F₂及其水合物形式;随着时间增长,还伴生有U₃O₈, UO₂, UO₃等多种铀化合物;加热过程中, UF₄/KBr的水解产物发生相互转化反应,其中形成的铀酰化合物最后全部转变为铀的氧化物形式.

关键词: UF₄, FT-IR, 水解反应, 转化行为

Abstract:

The hydrolyzation reaction and thermal transformation of UF₄/KBr in air at ambient temperatures were studied by in-situ transmission Fourier transform infrared (FT-IR) spectroscopy. The infrared spectra for a series of different compounds containing uranium before and after reaction were obtained. Following hydrolysis of UF₄/KBr in air, the primary products were UO₂F₂ and their hydrolysates. Other products, including U₃O₈, UO₂, and UO₃, appeared with increased reaction time. During the heating process, the hydrolysates of UF₄/KBr reacted with each other, finally yielding only uranium oxides.

Key words: UF₄, FT-IR, Hydrolyzation reaction, Transformation behavior
