SIGNIFICANCE AND USESIGNIFICANCE AND USE
Iodine may be used as a disinfectant in drinking and swimming pool waters. Unlike chlorinated pools, water treated
with iodine decrease eye irritation among swimmers and
provides a disinfectant more stable to adverse conditions.
However, iodine levels in the water must be frequently
checked to maximize its given purpose.
The Hanna Iodine Test Kit employs a color cube to determine the iodine content in water. The kit is compact and is
practical for field use. No chlorine or bromine can be present
in the water sample for this test to work properly.

The iodine is measured by a colorimetric method. The
sample is initially treated with a phosphate buffer to a pH
of approximately 6.3. The addition of DPD (N,N-diethyl-pphenylenediamine) is immediately oxidized by iodine
producing a reddish color. The color intensity of the solution
determines the iodine concentration.
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Add 7 drops of Reagent 1 and 3 drops of Reagent 2 in
the color comparator cube and mix by carefully swirling
the cube in tight circles.
• Fill the color cube with water
sample to the 25 mL mark.
• Cap and invert several time to mix.
• Determine which color matches the solution
in the cube and record the results as mg/L
(or ppm) iodine.
