摘　　要：本文详细地研究了应用鲁米诺-NaBrO_3-OH^-化学发光体系流动法测定痕量钌的最佳反应条件,探讨了该化学发光反应的机理,合理地解释了一些实验现象,建立了测定痕量钌的新方法,并有很好的选择性。方法已用于测定铬铁矿和镍铜锍扣中钌的测定,获得了满意的结果,其检出限达到0.8ng/ml,相对标准偏差为3％～7％,回收率在94％～107％之间。The optimum condition for the determination of trace ruthenium with Luminol-Na_2BrO_3-OH-chemiluminescence system was studied, and the mechanism of the chemiluminescence reaction was suggested. The method has been applied to the determination of ruthenium in mineral samples and fire-assaying samples with the detection limit of 0.8 ng/ml, relative standard deviation of 3%-7% and recovery of 94%-107%.
