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.
• 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.

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.
