摘要：
A new reagent proflavine N, N, N', N'-tetraacetic acid (PTA) synthesized in our laboratory has been found useful as a chemiluminescence reagent for the determination of ruthenium (Ru) in pH 2.5 sulfuric acid solution containing acetone, it can be oxidized catalytically by hydrogen peroxide. With Ru(III) as catalyst, it emits light selectively. The linear range is between 2.0 x 10(-8) and 2.0 x 10(-5) g/ml. The detection limit and the recovery rate of the method are 1.0 x 10(-9) g/ml and 96.0-102%, respectively. The method has been satisfactorily applied to determine trace Ru(III) in synthesized sample.
