A spectrophotometric flow injection system is described for the determination of hydrazine,
involving oxidation of hydrazine by thallium (III) with concomitant formation of thallium (I).
The optimum analytical conditions have been established. The linear range for hydrazine is
25–500 ng ml− 1 with a detection limit of 20 ng ml− 1. The sampling frequency is 40±5
samples h− 1. The relative standard deviation for 100, 250 and 500 ng ml− 1 is 3.5, 2.6 and
1.8%, respectively. The method has been applied to the determination of hydrazine in ...
