摘要

Considering of the basic properties and also the two nitrogen atoms in the structure, hydrazine hydrate was employed to be an amine additive candidate, to build a Ru(bpy)_3~(2+)/hydrazine electrochemiluminescence (ECL) system, and ECL of Ru(bpy)_3~(2+) has been employed for the determination of hydrazine hydrate in the paper. The result demonstrated that the logarithmic ECL increasing (△ECL=ECLafter addition of hydrazine~ECLbefore addition of hydrazine) VerSUS the log- arithmic concentration of hydrazine hydrate is linear over a concentration range of 1.0×10~-9 to 1.0× 10~-5 mol/L, on both glassy carbon and Pt electrodes in a pH 9 phosphate buffer. The hydrazine hydrate detection limit was down to 1.0× 10~-9mol/L, comparatively lower than other detection methods. To check its applicability, the proposed method was applied to the determination of hydrazine hydrate added into a tap water sample with good reproducibility and stability. All these provide a possibility to develop a novel ECL detection method for hydrazine in water.
