The Potassium Iodide Starch test paper detects free Iodine, Chlorine and Peroxides in solution. Lower levels react with the strip at 5 – 10 ppm. Iodine requires approximately 60 seconds to react, and initial reactions show a slight blue color, while higher concentrations turn the strip from dark blue to purple. Our Potassium Iodide Starch Paper is also available in a military grade (See Additional Information).

Potassium Iodide Starch Test Paper
- Remove one Potassium Iodide Starch test paper from the vial, being careful not to touch the paper anywhere other than where you grasp it.
- Dip the paper strip into the solution to be tested for 1-2 seconds.
- Remove the strip and shake off any excess liquid.
- Chlorine and Peroxides react immediately, while Iodine requires approximately 60 seconds. Initial reactions show a slight blue color, while higher concentrations turn the strip from dark blue to purple.
- The upper limits for chlorine and peroxides are between 400 to 450 ppm, and the upper limits for Iodine are at 50 to 100 ppm.

Product Documentation
Is it recommended to dip the Potassium Iodide Starch paper in 3N HCl before using the test paper?
The potassium iodide test papers use the potassium iodide starch reaction. The iodide is oxidized to iodine that then reacts with the starch to form the blue/purple color. The strips can be used directly in solution being tested. There is no need to wet them with acid that we know of. These strips will react once the contact the solution. Be aware that concentrated solutions may immediately “bleach out” the strip. This usually results in a telltale stripe at the water/dry strip interface.
