摘要

采用电子吸收光谱法研究了氯化铀(IV)与氧在氯碱基熔体中的反应。实验在450 ~ 750℃的熔体中进行，熔体分别为LiCl-KCl、NaCl - CsCl和NaCl - kcl - CsCl共晶混合物。同时考虑了惰性气体稀释氧气和水蒸气的存在对氧化反应的影响。采用电子吸收光谱法研究了氯化铀(IV)与氧在氯碱基熔体中的反应。实验在450 ~ 750℃的熔体中进行，熔体分别为LiCl-KCl、NaCl - CsCl和NaCl - kcl - CsCl共晶混合物。同时考虑了惰性气体稀释氧气和水蒸气的存在对氧化反应的影响。

Reaction of uranium(IV) chloride with oxygen in alkali chloride melts: An electronic absorption spectroscopy study

Electronic absorption spectroscopy was applied for studying the reaction of uranium(IV) chloride with oxygen in alkali chloride based melts. The experiments were performed at 450–750 °C in the melts based on LiCl–KCl, NaCl– CsCl and NaCl–KCl–CsCl eutectic mixtures. Effect of diluting oxygen with an inert gas and presence of water vapor on the oxidation reaction was also considered.Electronic absorption spectroscopy was applied for studying the reaction of uranium(IV) chloride with oxygen in alkali chloride based melts.
