Potassium permanganate has strong oxidation and is often used as oxidants in the laboratory and industry, being sweet and astringent and is soluble in water with the solution being purple.
1.It can be used as oxidant, bleach, carbon dioxide refined beverage, deodorant, wood preservatives, adsorbents, disinfectants, pesticides, water purifiers, etc.
2.It can be used as the bleaching agent, oxidant and disinfectant. China provides that it can be used for the production of starch and wine with the maximum usage amount of 0.5g/kg; the wine residue (calculated on manganese) should not exceed 0.002g/kg.
3. In the chemical production, it is widely used as oxidants, such as oxidant for the manufacturing of sugar, vitamin C, isoniazid and benzoic acid; in medicine, it can be used as a preservative, disinfectant, deodorant and antidote; in water purification and wastewater treatment, it can be used as water treatment agent for oxidation of hydrogen sulfide, phenol, iron, manganese and organic, inorganic and other pollutants for odor control and decolorization; in gas purification, it can be used to remove trace sulfur, arsenic, phosphorus, silane, borane and sulfide; in the mining and metallurgy, it can be used for the separation of molybdenum from copper, removing the impurity in zinc and cadmium and the oxidant of compound flotation; it can also be used for the bleaching agent of special fabrics, wax, grease and resin and the absorbent of gas masks and wood and copper coloring agent. Food grade product can be used as bleaching agent, disinfectant, deodorant, water purification agents and refining agent of carbon dioxide beverage.
4. Disinfection antiseptic agent;
5. It can be used as analytical reagent, redox titrant, chromatographic analysis reagent, oxidant and pesticide, also used in organic synthesis.
