In this paper. it was found that the enhancing effect of hydrazine on the weak electrogenerated chemiluminescence (ECL) signal of the electrooxidation of luminol at a pre-anodized platinum electrode was stronger than that of hydrazine at a bare platinum electrode. Based on this finding and the combination of this finding with a flow-injection technique, a novel, sensitive and selective ECL method for hydrazine was developed. Under the optimum experimental conditions, the relative ECL intensity was linear with hydrazine concentration over the range 2.0 x 10(-8) - 5.0 x 10(-5) mol L(-1), with a detection limit of 6.0 x 10(-9) mol L(-1).
