High Purity AR Grade Fine Crystals KMN04 Potassium Permanganate (KMNO4) High Purity AR Grade Fine Crystals Purity: Min: 99.4% ( INDUSTRIAL PURITY AND GRADE ) Appearance: POWDERED Crystals Chemical Formula: KMN04 POTASSIUM PERMANGANATE USES Survival kits: Potassium Permanganate can be included in survival kits: for Water Purification, to aid in lighting fires, creating a visible trail on snow, as well as treatment for fungal diseases. Infections: Potassium Permanganate can be used as an antiseptic /disinfectant for the hands and for the treatment for fungal infections of the hands and feet. Fish: Effective against external fungi, bacteria and parasites, including gill flukes Analytical use: Potassium Permanganate can be used to quantitatively determine the total oxidisable organic material in an aqueous sample. Water Purification Potassium permanganate is a point-of-entry treatment method that oxidizes dissolved iron, manganese, and hydrogen sulfide into solid particles that are filtered out of the water. It can also be used to control iron bacteria growth in wells.
