SELECTIVE FLOW-INJECTION DETERMINATION OF HYDRAZINE

Operating conditions were determined for the flow-injection determinat ion of hydrazine as a 5,7-dinitrobenzofuran derivative, In studying th e effect of various compounds on die signal intensity in the spectroph otometric detection of the hydrazine: derivative in a flow-injection a nalysis (FIA) system, it was found that the solvent and the major cons tituents of the reaction mixture exhibit basic catalytic properties. F IA procedures were developed for determining hydrazine in mixtures wit h a detection limit of 0.012 mu g/mL and a throughput of 46 h(-1).
