Abstract
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.
