摘要
以工业汞灯为光源,在硝酸体系中采用光化学方法控制镎(Np)价态的研究中,应用分光光度法对Np的价态及Np的定量测定分析,探讨了Np的光化学机理,得出了Np(Ⅵ)的光化还原速率方程,为光化学分离和提纯Np提供了必要的信息。
Spectrophotometry was used in the photochemistry study of Np in the nitric acid system
to determine the valence state and the concentration of Np. An industrial mercury lamp was
used as a source. The photochemical mechanism for Np is discussed and the rate equation of
the photochemical reduction of Np (Ⅵ) in HNO_3 solution is proposed.
