Bromine is less volatile and more stable than chlorine. This
makes bromine a good choice as a disinfectant in pools and
a sanitizing agent in drinking water systems. Like chlorine
excess amounts can produce hazards. A daily monitoring of
bromine levels prevents adverse conditions and optimizes
its proper function.
The Hanna Bromine Test Kit determines the bromine level
in water with swift efficiency. The case is compact, which
makes the kit available for onsite tests.
No chlorine or iodine can be present in the water sample for
this test to work properly.

A colorimetric method measures the bromine concentration
via a color cube. The sample is adjusted to a pH of
approximately 6.3 pH with a phosphate buffer solution.
The addition of DPD (N,N-diethyl-p-phenlenediamine) is
immediately oxidized by bromine producing a reddish color.
The color intensity of the solution determines the bromine
concentration.
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Add 7 drops of Reagent 1 and 3 drops of Reagent 2 to
the color comparator cube and mix by carefully swirling
the cube in tight circles.

• Remove the cap from the plastic vessel. Rinse the plastic
vessel and fill to the 25 mL mark with water sample.
• Transfer the 25 mL water sample from the plastic vessel
into the color comparator cube. Replace the cap and
mix it by inverting several times.
• Determine which color band best matches the
solution in the vessel and record the results in
mg/L (ppm) bromine.
