Oxidation Power Of Ozone

Ozone gas (O₃) is a colourless gas with molecules consisting of 3 oxygen atoms and is located in the upper layers of the atmosphere. Ozone is the allotrope of oxygen, it is also defined as trioxygen. Under normal conditions, the amount of O₃ in the lower parts of the atmosphere is about 0.4 ppm. However, the amount of ozone increases where there is smoky fog.

Ozone exceeding 0,12 level is considered harmful to health. Ozone is the main reason for the blue colour of the sky. Ozone gas, which turns into a dark blue colour in liquid form, protects the Earth against harmful ultraviolet radiation from the Sun. Ozone, which is formed by the breaking down of oxygen by the UV rays in the upper layers of the atmosphere and the lightning strikes in the lower layers, plays a very important role in cleaning the air. Oxidation power of ozone is widely used in food, textile, logistics and healthcare sectors in developed countries and as an alternative disinfectant.

Ozone, whose raw material is oxygen, is the only gas that cannot be stored. The reason why ozone cannot be stored is that ozone gas turns into its raw material oxygen over time in direct proportion to the temperature of the environment.
