SIGNIFICANCE AND USESIGNIFICANCE AND USE

SIGNIFICANCE AND USESIGNIFICANCE AND USE

In nature, the ammonia level in water can vary. Ground
water normally contains ammonia due to bacterial decay of
plants and animals. However, the presence of ammonia in
surface water may be evidence of sanitary pollution due to
waste discharges or natural causes.

The Hanna Ammonia Test Kit determines the ammonia
concentration in water in several easy steps. The kit is
portable and can be used in the field as well as in the
laboratory.

* mg/l is equivalent to ppm (parts per million)

CHEMICAL REACTIONCHEMICAL REACTION

CHEMICAL REACTION

CHEMICAL REACTIONCHEMICAL REACTION

The ammonia level in mg/L (or ppm), ammonia as nitrogen
is determined by a colorimetric method.

The Nessler reagent reacts with ammonia, under strong
alkaline conditions, to form a yellow colored complex (see
equation below). An addition of Reagent 1 for Sea Water
inhibits precipitation of calcium and magnesium ions due to
the presence of the alkaline Nessler reagent.

The color intensity of the solution determines the ammonia
concentration

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT

• Remove the cap from the plastic
vessel. Rinse the plastic vessel
with water sample before filling
it up to the 10 mL mark.

• Add 5 drops of Ammonia Reagent 1 for Sea Water,
replace the cap and mix by carefully swirling the vessel
in tight circles.

• Add 8 drops of Nessler Reagent, replace the cap and
mix by carefully swirling the vessel.

• Remove the cap and transfer the solution into the color
comparator cube. Wait for 5 minutes to allow color to
develop.

• It is better to match the color with a white sheet at
about 10 cm behind the comparator.
