Abstract
A new kinetic spectrophotometric method for the determination of hydrazine is described. The method is based on the inhibitory effect of hydrazine on the reaction of neutral red with nitrite in acidic media and 28 degrees C. A product from the reaction of neutral red with nitrite was used to monitor the reaction spectrophotometrically at 352 nm. Hydrazine can be determined in the range 4.7 x 10(-6) similar to 3.1 x 10(-5) mol/L with a detection l imit of 3.1 x 10(-6) mol/L. The method was applied to the determination of hydrazine in water samples.
