The permanganate index is a common index to reflect the pollution of organic and inorganic oxidizable substances in the water body, which is defined as: under certain conditions, potassium permanganate is used to oxidize some organic matter and inorganic reducing substances in the water sample, and the equivalent oxygen amount is calculated from the amount of potassium permanganate consumed.

The potassium permanganate index cannot be used as an indicator of theoretical oxygen demand or total organic matter content, because under the specified conditions, many organic compounds can only be partially oxidized, and volatile organic compounds are not included in the measured values.

Chemical oxygen consumption measured with potassium permanganate solution as an oxidizing agent was formerly known as manganese chemical oxygen consumption. In China's new environmental water quality standards, this value has been renamed the permanganate index, and only the value measured by the acid potassium dichromate method is called chemical oxygen demand. The International Organization for Standardization recommends that the potassium permanganate method is limited to the determination of surface water, drinking water and domestic sewage, and is not suitable for industrial wastewater.

Introduction to potassium permanganate

Potassium permanganate is a strong oxidizing agent with the chemical formula KMNO4 and is a black-purple crystal. Wheel Jingqin with blue metallic luster, odorless, contact with some organic matter or easy oxides, easy to occur, soluble in water, lye, slightly soluble in methanol, acetone, sulfuric acid. In chemical production, it is widely used as an oxidizing agent.

Potassium permanganate has strong oxidizing properties and is commonly used as an oxidant in laboratories and industries, and decomposes when exposed to ethanol manuscript covers. It slowly decomposes into manganese dioxide, potassium salts and oxygen in acidic media. Light has a catalytic effect on this decomposition, so it is often stored in brown bottles in the laboratory.

As can be seen from the elemental potential diagram and the oxidation state diagram of the free energy, it is extremely oxidizing. In alkaline dissolved wax solution, its oxidation is not as strong as in acidity.
