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 (Delta ECL = ECLafter addition of hydrazine -aEuro parts per thousand ECLbefore addition of hydrazine) versus the logarithmic concentration of hydrazine hydrate is linear over a concentration range of 1.0 x 10(-9) to 1.0 x 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 x 10(-9) mol/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.
