Unveiling the Science of Hydroxyl Radicals: How UV Light and Moisture Purify Your Indoor Space
Hydroxyl radicals are highly reactive molecules composed of one hydrogen and one oxygen atom, chemically represented as OH•. They play a vital role in the natural cleaning and purifying of the environment by oxidizing and breaking down a wide range of pollutants, making them harmless.
The Science of Hydroxyl Radicals
Hydroxyl radical generators, use a process called photocatalytic oxidation to create hydroxyl radicals within an indoor space. This process involves the following steps:
-
UV Light Activation: Hydroxyl generators are equipped with UV lamps or bulbs. When these lamps emit ultraviolet (UV) light, it interacts with atmospheric moisture (water vapor) in the indoor air.
-
Photocatalysis: UV light energizes the water vapor, splitting it into hydrogen and oxygen atoms. This reaction leads to the formation of hydroxyl radicals (OH•) from the hydrogen and oxygen atoms.
-
Continuous Cascade: Once generated, these hydroxyl radicals are released into the indoor air. They are highly reactive and continuously cascade through the room, seeking out and neutralizing pollutants, including bacteria, viruses, mold spores, and volatile organic compounds (VOCs) in the air and on surfaces.
By continuously releasing hydroxyl radicals, these generators mimic the natural process that occurs outdoors due to the interaction of UV light from the sun and atmospheric moisture. This cascade of hydroxyl radicals helps cleanse the indoor environment, making it safer and more healthy.
