SIGNIFICANCE AND USE SIGNIFICANCE AND USE SIGNIFICANCE AND USE SIGNIFICANCE AND USE SIGNIFICANCE AND USE
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.

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.
