Flow-injection electrogenerated chemiluminescence detection of hydrazine based on its in-situ electrochemical modification at a pre-anodized platinum electrode

Abstract

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 × 10−8–5.0 × 10−5 mol L−1, with a detection limit of 6.0 × 10−9 mol L−1.
