Flow injection chemiluminescence determination of hydrazine

A sensitive and selective flow injection chemiluminescence method for the determination of hydrazine over the range 1×10−6−5×10−5 M is described. The method is based on the chemiluminescence emitted during the oxidation of hydrazine by N-bromosuccinimide in alkaline medium in the presence of dichlorofluorescein as sensitizer. The presence of citrate prevents the precipitation of some cations in the reaction medium and also causes an enhancement...
