TECHNICAL DATA SHEET Potassium Monopersulfate compound


Potassium Monopersulfate compound

Product Introduction

Potassium Monopersulfate compound is a free flowing, white granular, and soluble in water (20℃, 256 g/L). The composition of Potassium Monopersulfate compound includes Potassium hydrogen peroxymonosulfate(KHSO5), Potassium bisulfate(KHSO4) and potassium sulfate(K2SO4). Potassium Monopersulfate compound has relatively high redox potential. Therefor it is a highly effective oxidant and disinfectant.

Basic Information

Name: Potassium Monopersulfate compound; PMPS; KMPS; pentapotassium bis(peroxymonosulphate) bis(sulphate);  potassium peroxymonopersulfate; potassium monopersulfate triple salt; 2KHSO5/KHSO4/K2SO4; OXONE; CAROAT

CAS: 70693-62-8 / Molecular Formula: 2KHSO5•KHSO4•K2SO4 / Molecular Weight: 614.7


1, Potassium Monopersulfate is a new type of active oxygen disinfectant, has a very strong and effective non-chlorine oxidation ability, its aqueous solution is acidic, very suitable for a variety of water disinfection, after dissolution, produce a variety of high activity small molecules Derivatives such as free radicals and active oxygen, do not form toxic by-products in water, and are extremely safe. Therefore, they are widely used in industrial and agricultural production. Their application fields include disinfection of drinking water, disinfection of hospital sewage, disinfection of domestic sewage, and livestock Poultry and aquaculture disinfection, oral cleaning, disinfection of swimming pools and hot hub water, circuit board etchants.

2, Substrate Improvement (oxidation, detoxification): Potassium monopersulfate potential value up to 1.85V, its oxidizing capacity exceeds most of the oxidants such as chlorine dioxide, potassium permanganate, TCCA, hydrogen peroxide, the potential value can oxidize most organic matter, reduce the oxygen consumption factor, and reduce the oxygen debt of the sediment, and can oxidize the divalent iron in the water body into ferric iron, divalent manganese into manganese dioxide, nitrite into nitrate, sulfide(hydrogen sulfide) into sulfate, which eliminates the damage of these substances to aquatic animals and repairs the black odor of the sediment. At the same time, potassium monopersulfate can degrade the residue chloramine after use of the chlorine preparation to reduce toxic residues.

3, Sterilization: In the process of disease occurrence, farmers still cannot treat diseases by using various disinfectants. The main reason is that long-term use of the same disinfectant leads to drug resistance of pathogenic bacteria. Potassium monopersulfate does not cause resistance to bacteria and viruses due to its unique bactericidal mechanism.

4, Water Quality Improvement: potassium monopersulfate not only can kill algae and other plankton, but also eliminate biotoxins such as algal toxins, often used in human and livestock drinking water treatment, mild nature, good safety. In pond culture, the water body is not only the living place of fish, but also the disposal place of “garbage” such as feces and residual baits. Due to the high density of culture, the self-purification ability of water bodies is limited, and water quality often appears abnormal, such as black water stinky water, thick green water, and algae. Potassium monopersulfate has strong oxidizing properties, can supplement the active oxygen deficiency in the water body, and at the same time oxidize the organic matter, ammonia nitrogen, sub-salt, hydrogen sulfide and other substances that are harmful to fish health due to insufficient oxygen supply, and achieve the purpose of water quality control. In addition, potassium monopersulfate has a good degradation effect on a large amount of algal toxin released under the conditions of algae and water bloom. Therefore, after the use of potassium monopersulfate, the water quality is obviously refreshed. If the fish is anorexia caused by water quality problems, the potassium monopersulfate composite powder has an excellent effect.

Product Usage

Potassium Monopersulfate compound, a stable, convenient and excellent acidity oxidant, is widely used in industries. It is used in oral hygiene, pool and spa water disinfection, water treatment, aquaculture, PCB etchant, Pulp bleach, wool fabrics shrink treatment agent, precious metal refining agent. Potassium Monopersulfate compound is also used in organic synthesis, such as epoxidizing the double bonds of organic molecule, or as initiator in many radical polymerizations. In addition, Potassium Monopersulfate compound can oxidize the hydrogen sulfide or sulfur-containing substances in the waste water, provide oxygen in aquaculture, and bleach to remove stains at low temperature.
