Introduction
National Standard of the People's Republic of China GB/T 1608—2017 Industrial Potassium Permanganate
Standard Background and Technical Evolution
The GB/T 1608 series of standards has undergone several revisions since its first release in 1986. The 2017 revision mainly adds product types (Type I and Type II), adds heavy metal indicators such as cadmium, chromium, and mercury, as well as parameters such as fluidity, moisture, and particle size, and optimizes the test methods.
| Items | Indicator requirements | |||
|---|---|---|---|---|
| Mass fraction of potassium permanganate (KMnO₄) (%) | Type I superior product | Type I qualified product | Type II product | |
| - | 99.4 | 99.2 | 97.5 | |
| Mass fraction of chloride (Cl) (%) | 0.01 | 0.02 | - | |
Application fields and technical requirements of potassium permanganate
Industrial potassium permanganate is widely used in the fields of chemical industry, metallurgical industry, environmental protection, agriculture and breeding, and is mainly used as an oxidant, disinfectant and water treatment agent.
Actual application case: water treatment field
In the treatment of domestic water, type II quicksand potassium permanganate is particularly suitable for rapid oxidation reactions due to its high activity and good fluidity. For example, in the process of drinking water purification, potassium permanganate can effectively remove iron, manganese ions and organic pollutants in water.
Standard Implementation Recommendations
- Manufacturers should establish a sound quality control system to ensure that product indicators meet the requirements of GB/T 1608-2017.
- Testing agencies should be equipped with advanced atomic absorption spectrometers and ICP-AES equipment to accurately determine the heavy metal content.
- When using potassium permanganate, users should strictly abide by the safety operating procedures and avoid contact with reducing agents and organic matter.
