钌(Ⅱ)-联吡啶—α-羟基羧酸—Ce(Ⅳ)偶合化学发光反应机理研究
A Study on Mechanism of Coupled Chemiluminescent Reaction of Ru(2,2’-bipyridine)32+-a-hydroxy Acid-Ce(IV)
【摘要】 系统地研究了Ce(Ⅳ),H2SO4,Ru(bipy)32+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)32+,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.
