, is added to the water in high pressure boilers to reduce
corrosion by acting as an oxygen scavenger.
APPLICATION: Water and boiler water, industrial waste water.
RANGE: 0.00–1.00 Hydrazine
METHOD: p-Dimethylaminobenzaldehyde reacts with hydrazine under
acidic conditions to form a yellow color in proportion to the
amount of hydrazine present.
SAMPLE
HANDLING &
PRESERVATION: Samples should be analyzed as soon as possible after
collection due to the ease with which hydrazine becomes
oxidized. Acidification of the sample may increase the time
between collection and analysis.
INTERFERENCES: The substances normally present in water do not interfere
with the test, with the exception of strong oxidizing agents.
