It was observed that hydrazine could enhance the chemiluminescence (CL) intensity of tris-(1,10 phenanthroline)ruthenium(Ⅱ) (Ru( phen)3^2+ )- Cerium( Ⅳ ) ice( 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^-3g·L^-1 and 1. 8×10^-6g·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. 展开更多
