Potassium persulfate disinfectant potassium persulfate compound salt

  Potassium persulfate disinfectant potassium persulfate compound salt
Potassium monopersulfate is an inorganic peroxide, also known as potassium monopersulfate
It exists in the form of trihydrate combined with potassium bisulfate and potassium sulfate
Therefore, it is called potassium monopersulfate composite salt
The molecular formula of the composite salt is 2khso5 & middot; KHSO4· K2SO4 with molecular weight of 614
7
It is a white powdery solid that can flow freely and is easily soluble in water
It is usually stable in the solid state, decomposes slowly and does not produce harmful substances
Potassium monopersulfate compound salt is a new type of special disinfectant for drinking water, which is the first and original non chlorine compound reactive oxygen species in China

1
Reduce the microbiological safety risk of drinking water: the potassium bisulfate composite powder dissolves in water and releases reactive oxygen species [O], and generates various high-energy and active small molecule free radicals, new ecological atomic oxygen, oxygen free radicals, hydroxyl free radicals (& middot; oh) and sulfuric acid free radicals (SO4 & minus; & middot;) through chain reaction with high-energy activator And other active ingredients, so as to become a high-efficiency oxidizing disinfectant, which has a wide range of microbial killing effects, including the inactivation of chlorine resistant bacteria in water supply bodies and water supply networks such as bacteria, spores, viruses and fungi
2
Decomposition of organic pollutants: the potassium bisulfate composite powder releases sulfuric acid free radicals after dissolving in water
The standard oxidation potential of sulfate free radicals E0 = 2
5 ~ 3
1 can oxidize some organic pollutants that cannot be oxidized by hydroxyl free radicals E0 = 2
80, decompose them into water, carbon dioxide and simple inorganic substances, degrade residual pesticides and heavy metals, and solve the acute and chronic poisoning problems caused by chemical pollution

3
Algae removal and algal toxin decomposition: the natural degradation process of algal toxin in water is very slow
When the content in water is 0
005mg/l, only 10% is absorbed by particles in water after three days, and 7% is precipitated with sediment
Microcystins have high heat resistance
Heating and boiling can neither destroy nor remove the toxin, and the conventional treatment process of tap water (coagulation sedimentation, filtration and disinfection) can not effectively remove the algal toxin in the water
A large number of literature and field experiments show that potassium bisulfate complex salt can effectively remove algae and decompose algal toxins

Sterilization principle
In terms of molecular structure, potassium bisulfate molecule is very similar to peracetic acid, and the peroxide bond is connected with sulfur atom and carbon atom respectively
However, potassium bisulfate is inorganic, and its effective disinfection component is single persulfate ion (soh5 & mdash;), Its stability is better than that of peracetic acid

From the perspective of molecular structure, potassium bisulfate should be a neutral salt, and the acidity of its aqueous solution is caused by the dissolution of potassium bisulfate in the composite salt to produce hydrogen ions
However, the stability of Potassium Bisulfate under acidic conditions is much better than that under neutral conditions, and it will decompose rapidly under alkaline conditions
Its mechanism of killing microorganisms can be explained as follows:
Under the condition of aqueous solution, potassium bisulfate releases neoecological oxygen and directly oxidizes microbial cell wall proteins

Release free hydroxyl, interfere with microbial enzyme system, and quickly lead to the inactivation of microbial protein molecules
Studies have shown that when potassium persulfate acts on small molecular organics, such as long-chain aldehydes and amines, free hydroxyl groups promote the reaction

Sterilization characteristics
The concentration of effective active ingredient (active oxygen) produced by this product reaches 7% - 9%
It only takes 15min to contact with water to effectively sterilize

New ecological oxygen [O] and its series of free radicals will be continuously and permanently produced through chain reaction in water, so it will maintain the bactericidal capacity in water for a long time

A variety of active ingredients coexist and the antibacterial spectrum is expanded, so that the product is effective against bacteria, spores, fungi and viruses

The effect of killing microorganisms is less affected by factors

No toxic or harmful & ldquo; Three to & rdquo; By products, only K and SO4 increase slightly (if added to the water body at the rate of 0
5ppm: the increase of K is 0
03ppm; the increase of SO4 is 0
06PPM)
