Ammonium persulfate is a Mineral composition. This substance is a strong oxidizer and it is widely used in the chemical industry.
(NH4)2S2O8 is the chemical formula of this substance. this mineral also has other names, including ammonium proxy disulfate, diammonium proxy disulfate, and diammonium per oxo disulfate. It is produced in powder form and white solid crystals. The color of this substance can be pale yellow or even colorless. Ammonium sulfate has high oxidizing power and can be used as a surface bleach or food preservative.
Physical and chemical properties:
Heat can cause ammonium proxy disulfate to decompose. At temperatures above 120 ° C, it releases toxic gases such as sulfur oxide, nitrogen oxide, and ammonia. From the dissolution of ammonium persulfate in water, an acidic solution is formed. Ammonium persulfate is hydrophilic and easily absorbs moisture. it Decomposes in a humid environment and releases hydrogen peroxide.
The physical and chemical properties of this material can be summarized in the table below:
|Molecular weight (g/mol)||228.18|
|Melting point (°C)||120|
|Boiling point (°C)||1388|
|Solubility in water (g/100 ml 25 °C)||80|
|PH (20 °C)||2.5|
Industrial ammonium persulfate is produced by the electrolysis method. To produce it, two substances, ammonium sulfate, and sulfuric acid are electrolyzed and then ammonium persulfate is produced by crystallization and separation operations.
The details of the production method of ammonium proxy disulfate can be explained as follows: by performing the electrolysis process on ammonium sulfate and sulfuric acid, an electrolytic liquid is obtained, then sulfuric acid reacts with ammonium sulfate and during the filtration, crystallization, separation, and centrifugation steps Purification and drying also turn into ammonium sulfate crystals.
Application and uses of ammonium persulfate:
The most important application of ammonium persulfate is in the production of detergents such as bleaches, soaps, and cleaners, in analytical chemistry, ammonium proxy disulfate is mainly used to identify and determine manganese.it is also used as an oxidizing agent and initiator in polymerization processes, for example, it is used as an initiator in the emulsion polymerization of monomorphemic chloride. In polymerization reaction, It is very important in the final properties of the product. Decreasing or increasing the starting value has a direct effect on the particle size and consequently on the final properties of viscosity and film formation properties.
Ammonium persulfate is used to resize yarn and cotton. In agriculture, it is used to produce chemical fertilizers and water-soluble sprays, fungicides, and herbicides. In the food industry, it regulates acidity and it is also used as a modifier of wheat and flour.
Other applications of this material are in the production of cosmetics, paints, and paper.

Ammonium persulfate can be harmful to health if safety precautions are not followed. As mentioned, it emits nitrogen oxide gases, sulfur oxides, and ammonia vapors from the heat, and if this substance enters the eye, it can cause irritation and inflammation.
Avoid eating this substance, because by eating ammonium sulfate, your stomach will start to bleed and may cause anesthesia, and its low use will cause narrowing of the esophagus and make it difficult for you to breathe. If the person is unconscious from swallowing, do not give him anything. If the person is conscious, rinse his mouth with plenty of water and then give him a glass of water. The use of nausea medication is prohibited in these cases.
Direct contact of ammonium sulfate with the skin causes itching, inflammation, and pain. Also, inhalation can cause a sore throat and respiratory problems, so working with this substance requires all safety and health tips, including the use of gloves, goggles, and Special clothing.
This material is explosive, high temperatures, and exposure to high heat and fire and also its combination with phosphorus and sulfur can cause it to explode.
Transporting and storage:
The storage area of Ammonium persulfate should be dry and free of moisture and it should be well ventilated. It should not be exposed to its vapors in any way. This material can be stored at room temperature, but care must be taken that it does not reach too much heat. Keep in a cool, dry place
Proper packaging and containers should be used for storage.
