Iodine Test Kit

ISTR3832R1 06/00 PRINTED IN ITALY

Iodine may be used as a disinfectant in drinking and swim-
ming 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 deter-
mine 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.

SIGNIFICANCE AND USE

CHEMICAL REACTION

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-p-
phenylenediamine) is immediately oxidized by iodine
producing a reddish color. The color intensity of the solution

determines the iodine concentration.

REFERENCES

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.
