Abstract A simple and sensitive flow injection method is described for the determination of
trace amounts of hydrazine, based on its inhibitory effect on the reaction between pyrogallol
red and iodate in hydrochloric acid media. The reaction was monitored
spectrophotometrically by measuring the change in absorbance of pyrogallol red at 470 nm.
The calibration graph was linear over the range of 0.050–1.20 μg/mL, with a limit of
detection of 0.03 μg/mL. The relative standard deviation for ten replicate measurements of ...
