本文研究了硝酸体系中,酸度,Np(Ⅵ)初始浓度和温度等因素对Np(Ⅵ)光化还原速率的影响。推导出Np(Ⅵ)的光化还原速率方程式 -((d[Np(Ⅵ)])/dt)=0.05766[Np(Ⅵ)][H~+]~(-1)所提出的反应机理能较好地符合实验结果。
In this paper, the effects of acidity, initial Np (Ⅵ) concentration and temperature on the photodecomposition rate of Np (Ⅵ) were studied. The photochemical reduction rate equation of Np (Ⅵ) - (d [Np (Ⅵ)]) / dt) = 0.05766 [Np (Ⅵ)] [H ~ +] -1 is proposed. Better in line with the experimental results.
