Iodine Test Paper

Iodine Test Paper

The Iodine test paper detects available Iodine in solutions in increments of 0, 12.5, 25, & 50 ppm. Disinfection with Iodine occurs between 12.5 ppm and 25ppm. This is an older method for sanitizing utensils and dishware used in the restaurant trade.

  2. Dip the strip into the solution being tested for 60 seconds without agitation.

Product Documentation

Why isn't my Iodine test paper working?

Iodine solutions prepared at the concentrations on the color chart should react with the paper. It is important to dip the strip the full 60 seconds. The reaction takes place very slowly.

On the other hand, the reaction of the same iodine paper to chlorine is very fast. If you have access to regular household bleach (typically 5-8% available chlorine depending on the manufacturer) you can take a tablespoon of bleach and mix it into a gallon of water. Using the test papers, the iodine strip should develop a deep blue/purple color. If it does not, then something is wrong with the test papers. If it does develop the deep blue/purple color with chlorine, then the problem is not the strips.
