Potassium Peroxymonosulfate Product Description
Potassium peroxymonosulfate, also known as potassium monopersulfate or potassium peroxodisulfate, is a strong oxidizing agent commonly used in a variety of applications.
It is a white crystalline powder that is very soluble in water and stable at room temperature. One of the most common uses of potassium persulfate is as an oxidizing agent in swimming pool and spa water treatment. It helps remove organic pollutants, kills bacteria, eliminates algae and improves water clarity. It is usually sold under various brand names in granule or tablet form. Potassium peroxymonosulfate is also used as an oxidant and disinfectant in various industrial processes such as wastewater treatment, pulp and paper, and chemical synthesis.
Additionally, it is used in laboratory environments to clean and disinfect equipment and surfaces. It is important to take proper safety precautions when handling potassium persulfate. It may irritate the eyes, skin and respiratory system, so goggles, gloves and a mask are recommended. Proper disposal methods should also be followed to prevent environmental contamination. It is worth noting that potassium peroxymonosulfate should not be confused with potassium persulfate, another oxidizing agent with similar properties but a different chemical structure and application.

| Purification Methods |
This is a stable form of Caro's acid and should contain >4.7% of active oxygen. It can be used in EtOH/H2O and EtOH/AcOH/H2O solutions. If active oxygen is too low. it is best to prepare it afresh from 1mole of KHSO5, 0.5mole of KHSO4 and 0.5mole of K2SO4. [Kennedy & Stock J Org Chem 25 1901 1960, Stephenson US Patent 2,802,722 1957.] A rapid preparation of Caro's acid is made by stirring finely powdered potassium persulfate (M 270.3) into ice-cold conc H2SO4 (7mL) and when homogeneous add ice (40-50g). It is stable for several days if kept cold. Keep away from organic matter as it is a STRONG OXIDANT. A detailed preparation of Caro's acid (hypersulfuric acid, H2SO5) in crystalline form m ~45o from H2O2 and chlorosulfonic acid was described by Fehér in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 388 1963. |
