Fotodegradation is a chemical process in which a substance is broken down by the action of light. This process is significant in various fields, including chemistry, environmental science, and materials science. The term "fotodegradation" is derived from the Latin word "foto," meaning light, and the Greek word "degradatio," meaning degradation.

The mechanism of fotodegradation involves the absorption of photons by a molecule, which excites the molecule to a higher energy state. This excited state can lead to various chemical reactions, such as bond breaking, rearrangement, or oxidation. The products of fotodegradation are often less stable or more reactive than the original substance.

Fotodegradation is influenced by several factors, including the wavelength and intensity of the light, the chemical structure of the substance, and the presence of other substances that can sensitize or inhibit the process. It is a significant factor in the degradation of organic pollutants in the environment, as well as in the degradation of materials used in various applications, such as plastics and dyes.

In environmental science, fotodegradation is a key process in the degradation of organic pollutants, such as pesticides and pharmaceuticals, in water and soil. It is also a significant factor in the degradation of materials used in various applications, such as plastics and dyes. In materials science, fotodegradation is a concern in the development of materials that are resistant to light-induced degradation.

Fotodegradation is a complex process that involves the interaction of light with matter. It is a significant factor in the degradation of organic pollutants in the environment, as well as in the degradation of materials used in various applications. Understanding the mechanisms and factors influencing fotodegradation is crucial for developing strategies to mitigate its effects and for designing materials that are resistant to light-induced degradation.
