SIGNIFICANCE AND USE

The disinfectant properties of iodine have led to its use as

an alternative to chlorine and bromine.
However, its toxic and corrosive properties and the difficulties

of dissolving it in water has limited a more wide-spread
application. One of its most common application is in
poultry industry process water.
Note: mg/L is equivalent to ppm (parts per million).

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT

• Fill the color comparator cube with

5 mL of sample (up to the mark).

• Add 1 packet of HI 93718-0 reagent, replace the cap

and shake well.

• Wait for 2 minutes to allow color

to develop.

• Determine which color matches the solution in the vessel

and record the result as mg/L (or ppm) of Iodine.

Note: It is better to match the color with a white sheet

placed at about 10 cm (4") behind the comparator.

5 mL

10 cm

The reaction between iodine and the reagent causes a
reddish tint in the sample. The amount of color developed is
proportional to the concentration of iodine present in the

aqueous sample.
