| 摘 要： | 系统地研究了Ce(IV), H2SO4, Ru(bipy)3^2^+和5种α-羟基羧酸对Ce(IV)氧化钌(II)-联吡啶化学发光反应速率的影响。结果表明,在选定的试验条件下, 化学发光反应速率分别与Ce(IV),Ru(bipy)3^2^+, 5种α-羟基羧酸的浓度和1/H2SO4]^2成正比, 据此提出了偶合化学发光反应机理, 推导得到的反应速率方程与实验结果吻合。

| Abstract: | The effect of Ru(bipy)32+, H2SO4 ,Ce(IV) and a - hydroxy acids on CL reaction rates between Ce( IV )and Ru(bipy)32+ (bipy=2,2' - bipyridine) was systematically studied. The results was shown that the chemiluminescence reaction rates were proportional to the concentration of Ru(bipy)32+ ,Ce(IV) and a - hytroxy acids, respectively. It was inversely proportional to the square of the concentration of H2SO4.The coupled chemiluminescent reaction mechanism and rate equation were proposed,which was consistant with our experimental results. |
