Özet:

 


Hydrazine
is an inorganic chemical compound with the chemical structure N2H4.
Hydrazine a colorless flammable liquid compound. Hydrazine is very toxic and
unstable compound, also hydrazine is a strong reducing agent. This compound
easily ignites in the air, generating a large amount of heat and the
composition of nitrogen gas and water. Symptoms of acute (short-term) exposure
to high levels of hydrazine may include irritation of the eyes, nose, throat,
dizziness, headache and nausea. Acute exposure can also damage the liver,
kidneys and central nervous system. Cases of lungs, liver, spleen and thyroid
infection in animals exposed to hydrazine have been reported by inhalation.
Increased lung injury, nasal cavity, and liver tumors were observed in rodents
exposed to hydrazine. This work involves the development of a fast and
sensitive spectrophotometric method for the determination of trace of
hydrazine, the method based on the reduction of ferric ions by hydrazing to
ferrous ions, and finally the later reacts with the reagent (2,2'-bipyridyl) at
60°C to form a stable red-pink complex, this complex is soluble in water and
gave absorption maxima at 523 nm. Beer's law was agreed with range (50-800) µg
of hydrazine per 25 ml (i.e: 2-32 ppm), with a corresponding molar absorptivity
of 5.6×103 l.mol-1.cm-1, Sandell's sensitivity
index of  0.02 µg.cm-2 limit
of quantitation of 0.3 µg/ml, limit of defection 0.1 µg/ml , and finally
average relative standard deviation of +1.25%, depend on the
concentration level. This method had been applied successfully to determination
of hydrazine amount in different samples water (tap water, river water and sea
water).
