Abstract: | A sensitive kinetic method for determining low levels of hydrazine has been described. The method is based on the measurement of the rate of the reaction between hydrazine and Mo(VI) in the presence of hydrochloric acid. The redox reaction was monitored spectrophotometrically at 710 nm. The variable-time and fixed-time methods were used. The calibration graph was linear for hydrazine concentrations of 1.0 × 10−4-1.4 × 10−2 M, using the fixed-time method of analysis. The method is simple, rapid, precise, sensitive and widely applicable. |
