研究了硝酸介质中亚硝酰钌配合物的光分解反应，测定了亚硝酰钌配合物的紫外吸收光谱。实验结果表明：在低压汞灯２５４ｎｍ的紫外光照射下，硝酸介质中亚硝酰钌配合物的光分解反应属表观准一级反应；在ｃＨＮＯ３＜２ｍｏｌ／Ｌ时，反应速率常数随硝酸浓度的增加而增大，在ｃＨＮＯ３＞２ｍｏｌ／Ｌ时，反应速率常数随硝酸浓度增大而减小。温度在１０—４０℃时，速率常数随着温度的上升而减小。
The photodecomposition reaction of nitrosyl ruthenium complexes in nitric acid media was studied and the UV absorption spectra of the ruthenium nitrosyl complexes were determined. The experimental results show that the photodegradation of nitrosyl-ruthenium complexes in the nitric acid medium is an apparent quasi-first-order reaction under the UV light irradiation of 254 nm under the low-pressure mercury lamp. When cHNO3 <2mol / L, the reaction rate constant increases with the nitric acid concentration The increase of nitric acid concentration decreases the reaction rate constant at cHNO3> 2mol / L. The rate constant decreases with increasing temperature at 10-40 ℃.
