What does ozone eat?

Published in Atmospheric Chemistry 2 mins read

Ozone doesn't "eat" anything in the way that living organisms do. Instead, ozone molecules react with other substances, breaking them down through oxidation.

Ozone (O3) is a highly reactive form of oxygen. This reactivity means it readily participates in chemical reactions. It's a powerful oxidizing agent, meaning it can accept electrons from other molecules. This process often results in the decomposition or alteration of those molecules.

Here's a breakdown of what ozone reacts with:

  • Air pollutants: Ozone reacts with various air pollutants, such as nitrogen oxides (NOx), volatile organic compounds (VOCs), and carbon monoxide (CO). These reactions can help to remove some pollutants from the air, but they can also create other pollutants like ground-level ozone itself.

  • Bacteria, viruses, and mold: Ozone is used as a disinfectant because it effectively kills bacteria, viruses, and mold by oxidizing their cellular structures. This is why it is sometimes used in water treatment and air purification.

  • Organic matter: Ozone can react with organic matter, breaking it down into smaller, less harmful substances. This is utilized in wastewater treatment to remove contaminants.

  • Materials like rubber and plastics: Ozone can degrade certain materials over time. This is why ozone generators should be used with caution around items that could be damaged by prolonged exposure.

In summary, ozone doesn't "eat," but it reacts with many different substances, oxidizing and breaking them down.
