Ozone oxidation mechanism

The strong oxidation of ozone is due to the strong electron - or protophilic properties of the oxygen atoms in the ozone molecule. After ozone decomposition, it can form a strong oxidizing group - hydroxyl radical in water, which can quickly remove organic pollutants in wastewater, and decompose itself into oxygen, which will not cause secondary pollution.

It is currently believed that ozone reacts with organic matter in two ways:

(1) Ozone reacts directly with organic matter in water in the form of oxygen molecules. The method has strong selectivity, generally attacks organic compounds with double bonds, and is easier to react with aromatic hydrocarbons and unsaturated aliphatic hydrocarbons.

(2) Under alkaline conditions, ozone decomposition in water produces highly oxidizing hydroxyl radicals and other intermediate products, and the intermediate products react with organic compounds.
