本工作研究铀(硝酸铀酰)存在条件下Tc(Ⅶ)与甲基肼(硝酸甲基肼,下同)在硝酸介质中的反应,实验考察铀对Tc(Ⅶ)与甲基肼的反应的影响,并进一步考察酸度、还原剂浓度、温度等因素的影响。铀对反应的影响如图1所示,实验结果表明,铀对Tc(Ⅶ)与甲基肼在硝酸中的反应有显著的促进作用。铀浓度越高,Tc(Ⅶ)与甲基肼的反应越快。 In this work, the reaction of Tc (Ⅶ) with methyl hydrazine (methyl-hydrazine nitrate, the same below) in nitric acid medium was studied in the presence of uranium (uranyl nitrate) The effects of acidity, reductant concentration, temperature and other factors were further investigated. The effect of uranium on the reaction is shown in Figure 1. The experimental results show that uranium can significantly promote the reaction of Tc (Ⅶ) with methyl hydrazine in nitric acid. The higher the uranium concentration, the faster the reaction of Tc (Ⅶ) with methylhydrazine.
