Fe（Ⅲ）－4，7－二苯基邻菲罗啉配合物光化学还原反应的研究

Photoreduction of Iron(Ⅲ) Bathocuproine Complex

Ｆｅ（Ⅲ）－４，７－二苯基邻菲罗啉（简称ＢＰＴ）可形成无色的Ｆｅ（Ⅲ）－ＢＰＴ配合物。在紫外光照射下，上述配合物可发生光化学还原反应，生成红色的Ｆｅ（Ⅱ）－ＢＰＴ配合物。本工作以低压汞灯作为光源，研究了溶液酸度、各种有机酸、表面活性剂和醇等对体系光化学还原反应速率的影响规律，并初步探讨了其反应机理。实验表明，Ｆｅ（Ⅲ）－ＢＰＴ体系的光化学还原反应为零级反应，各种有机酸、表面活性剂和醇对光化学还原反应速率有明显影响。

Iron(Ⅱ) Bathocuproine complex is produced by Iron(Ⅲ) Bathocuproine.The complex is readily reduced by ultraviolet light.The effects of various carboxylic acids,pH value of the solution,various nonionic surfactants and alcohols on the rates of the photoreduced reaction for Fe(BPT) 3+ 3 are investigated,and the mechanism is preliminarily discussed.
