Potassium permanganate is a very strong oxidizing agent. Its primary use is in the treatment of industrial and domestic water to remove iron, manganese, hydrogen sulfide, taste and odor.

CHEMetrics' permanganate test kits are applicable to monitoring the concentration of permanganate in feed solutions used to treat potable water and wastewaters.

The test method employs a titrimetric chemistry in which ferrous ammonium sulfate is the titrant. No additional indicator is required. A color change from clear to red signals the end of the test.  Results are expressed as percent (%) KMnO₄.
