【摘要】 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。更多还原

【Abstract】 The influence of the initial concentration of Np(Ⅵ) in nitric acid solution, temperature and acidity etc. on the photoreduction of Np(Ⅵ) has been studied in detail with mercury lamp. The rate equation of photoreduction of Np(Ⅵ) is formulated as follows._d[Np(Ⅵ)]/dt =0.05766[Np(Ⅵ)][H+]-1The photochemical reaction mechanism of Np suggested in this system can be interpreted satisfactorily by the experimental results.更多还原
