硝酸铀酰水溶液光化还原反应的研究具有重要的理论与实际意义,以激光来进行硝酸铀酰光化还原的研究尚未见报导。我们以 CW 氦-镉激光器(波长4416(?))作为光源,对以乙醇作还原剂的硝酸铀酰的光化反应进行研究。实验结果表明:铀(Ⅵ)的光化还原速率随硝酸浓度的增加而增加,至硝酸浓度为1 M 左右时达到最大值,然后随酸度的增加而下降;铀(Ⅵ)的光化还原速率随乙醇浓度
The study on the photochemical reduction of uranyl nitrate aqueous solution has important theoretical and practical significance. The study of laser photodegradation of uranyl nitrate has not been reported yet. We studied the photochemical reaction of uranyl nitrate with ethanol as a reducing agent using a CW helium-cadmium laser (wavelength 4416 (?)) As a light source. The experimental results show that the photochemical reduction rate of uranium (Ⅵ) increases with the increase of nitric acid concentration, reaches the maximum when the concentration of nitric acid is about 1 M, and then decreases with the increase of acidity. The photochemical reduction rate of uranium (Ⅵ) With ethanol concentration
