Colorimetric determination of Hydrazine
In acidic solution hydrazine reacts with 4-dimethylaminobenzaldehyde to form a yellow/orange colored compound.
Hydrazine is used to destroy residual oxygen in boiler feed and condensation water, for example in power plants, to avoid corrosion of the boiler casing. Reaction products are merely nitrogen gas and water, thus the salt load of the water is kept low.Because of its highly reactive properties, hydrazine is also used as fuel in aviation and astronautics.
Hydrazine is toxic, has shown to be cancerous in animal tests and has a highly toxic effect on water organisms. Hydrazine can be absorbed through the skin. Therefore, water and wate water with potential content of hydrazine must be determined.
