Potassium peroxymonosulfate|70693-62-8

Potassium peroxymonosulfate is an environmentally friendly and efficient water quality treatment improver with high active oxygen content, no side effects, easy to use, inexpensive and good bactericidal effect. Potassium peroxymonosulfate can be used as drinking water disinfectant, environmental disinfectant, able to prevent and control aquatic bacterial diseases. It is also used as water quality improver and aquaculture substrate improver in aquaculture industry. White powder, easily soluble in water, at 20 ℃, water solubility is more than 250g/L. Potassium bisulfate aqueous solution is acidic, poor stability in water, can not be stored for a long time. Usually it is more stable in solid state, dry powder is easy to decompose and react when the temperature is higher than 65℃, releasing oxygen and sulfide, but decompose in water releasing oxygen and potassium sulfate, not producing harmful substances. Strong oxidizing ability, its oxidizing potential energy is high, exceeding that of chloride, potassium permanganate, hydrogen peroxide, etc. It can oxidize chlorine ions in aqueous solution into chlorine gas, and it can oxidize organic substances such as alcohols and aldehydes into organic acids.

Basic Information

Name: Potassium peroxymonosulfate, potassium peroxymonosulfate, abbreviation: PMPS or KMPS

Molecular formula: 2KHSO5.KHSO4.K2SO4

Molecular weight: 614.7

CAS No.: 70693-62-8

EINECS: 274-778-7

Mechanism

Potassium peroxymonosulfate reacts with water, and when dissolved in water, it releases reactive oxygen species through chain reaction, and then forms hydroxyl radicals, hydrogen peroxide radicals, hypochlorous acid and other active ingredients. The hypochlorous acid and new ecological oxygen produced play the role of killing and inhibiting bacteria and diseases, can oxidize and chlorinate biological pathogens, inactivate pathogens, affect their metabolism, and cause the death of pathogens by cleavage. The organic acid and acidic environment produced by Potassium peroxymonosulfate have the effect of synergistic killing of pathogens, and the reaction process does not produce harmful substances, and the generated oxygen can also play a role in increasing dissolved oxygen.

Functional use

1, in the treatment of aquaculture wastewater, the use of persulfate treatment after 24 hours, can increase dissolved oxygen, reduce the oxygen debt of the water body and nitrite.

2, Potassium peroxymonosulfate can inhibit the growth and reproduction of harmful microorganisms in aquaculture water;

3, can quickly degrade ammonia nitrogen, nitrite, hydrogen sulfide and other toxic substances;

4, Degradation of various types of algal toxicity such as hepatotoxin produced by the death of algae;

5, repair the water body viscous, water turbidity, slate, black, heat, odor and other phenomena;

6, oxidizing and removing toxic and difficult to degrade organic pollutants in the water body, eliminating chlorine residue, activating chlorine, decomposing carcinogens such as combined chloramines produced by chlorination reaction, and avoiding their aggregation in the animal body;

7, detoxification of organic matter in the bottom mud of the pool, transforming the bottom organic matter into bait for sea cucumbers, shrimps, crabs, loaches and shellfish, improving the habitat environment and promoting animal growth;

8, Reduce the occurrence of shrimp pulling death and crab black bottom and black gill;

9, Reduce heavy metal ions in the water body through ion exchange, complexation, adsorption and other multiple effects.

10, Potassium peroxymonosulfate in bottom modification, persulfur and beneficial bacteria (photosynthetic bacteria, bacillus and lactobacillus) together, can accelerate the degradation of total nitrogen and total phosphorus of pond substrate, slow down the growth of total nitrogen and total phosphorus, so that more nutrients are released into the water body, supplying phytoplankton to be utilized, of which the synergism between persulfur and lactobacillus is the most significant effect, which can effectively control the nitrogen and phosphorus.

Cautions

Avoid mixing Potassium peroxymonosulfate with alkaline or reducing substances. Live bacteria can be used after 12 hours of use. If the bag rises, it is a normal phenomenon and does not affect the use effect.

Scope of application

Potassium bisulfate is suitable for the whole process of seedling and finished aquaculture of sea cucumber, jellyfish, shellfish, shrimp, crab, loach, eel, sea and freshwater fish.

Storage

Keep in cool, dry and ventilated warehouse, Potassium peroxymonosulfate is strictly prohibited to be stored with other chemicals. Keep away from fire source, combustible materials, etc.

Potassium persulphate kills all viruses, bacteria and their germs, mycoplasma, fungi and coccidian oocysts infecting humans and animals. Potassium peroxymonosulfate is effective in killing common E. coli, Riemeria duckii, Staphylococcus aureus, Salmonella, and Newcastle disease virus of chickens. African swine fever is a new infectious disease in China in recent years, and Potassium peroxymonosulfate is also said to be effective in killing African swine fever.
