摘要
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 photolysis of nitrosyl ruthenium complexes in nitric acid media has been investigated in detail using low pressure mercury lamp(254 nm).The UV spectra of nitrosyl ruthenium complexes is also studied.The experimental results show that the photolysis of nitrosyl ruthenium in nitric acid media obeys pseudo first order kinetics.The rate constant is affected by the concentration of nitric acid and has a maximum at 2 mol/L HNO 3.In temperature range from 10℃ to 40℃,the rate constant decreases with the increasing of the temperature.
