It was observed that hydrazine could enhance the chemiluminescence (CL) intensity of tris-(1,10-phenanthroline)ruthenium(Ⅱ)(Ru(phen)3 2+ )- Cerium(Ⅳ) (Ce(Ⅳ)) system, based on which, a novel CL system, Ru(phen)3 2+ -Hydrazine-Ce(Ⅳ), was established. This CL system was investigated and employed to detect hydrazine. Under the optimum experimental conditions, the linear range and detection limit of the proposed method are 2.0×10 -6 -2.0×10 -3 g·L -1 and 1.8×10 -6 g·L -1 , respectively. For 1.5×10 -5 , 1.5×10 -4 and 1.2×10 -3 g·L -1 hydrazine, the relative standard deviation (RSD) is 2.9%, 2.2% and 3.1%, respectively (n=11). The proposed method has been used to detect the content of hydrazine in the synthetic samples with satisfactory results.
