A hydroxyl generator utilizes what type of light to create hydroxyl radicals?

A hydroxyl generator uses ultraviolet (UV) light to create hydroxyl radicals. This process involves the photolysis of water molecules, where UV light provides the necessary energy to break down water into hydroxyl radicals. These radicals are highly effective at breaking down organic compounds and odors, making hydroxyl generators useful in restoration and remediation scenarios following fire or smoke damage.

The use of UV light is critical because it operates within a specific wavelength range that enhances the formation of these radicals. Other types of light, such as infrared or visible light, do not possess the right energy levels to facilitate this reaction effectively. X-ray light, while it also contains high energy, is not utilized for this purpose as it poses safety concerns and is not necessary for generating hydroxyl radicals in restoration processes. This ability of UV light to induce the formation of hydroxyl radicals is what makes it the ideal choice for hydroxyl generators in fire and smoke restoration applications.
