What are chlorofluorocarbons (CFCs)? Chlorofluorocarbons (CFCs) are a group of manufactured chemical compounds that contain chlorine, fluorine, and carbon. This group includes CFC-11, CFC-12, CFC-113, CFC-114, CFC-115, and many forms of Freon. They are colorless, odorless, nontoxic, nonflammable, and stable when emitted. When they are emitted and reach the stratosphere, they break apart and release chlorine atoms, which destroy the earthâs ozone layer. CFCs can last for more than 100 years in the stratosphere. Because they destroy the ozone layer, CFCs have been banned from production in the United States since December 31, 1995.
convert and stabilize the chlorine in the form of chloramine. Chlorine in chloramine can revert back to free chlorine and exert its oxidative activity. The process, however, is slow and only a small fraction of chlorine is released at a given time. In effect, chloramine functions like a slow release medication in the water disinfection process. Since chloramine is less reactive than free chlorine, it will not form
