Since the 1990s, many public systems have switched to inorganic chloramine, a chlorine derivative, to purify water supplies. Systems serving about 113 million people in the U.S. use this process.
Disinfection by-products (DBPs) are organic and inorganic compounds resulting from chemical reactions between organic and inorganic substances such as contaminates and chemical treatment disinfection agents, respectively, in water during water disinfection processes.
Chloramination is the treatment of drinking water with a chloramine disinfectant. [1] Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant. Chloramine disinfection is used in both small and large water treatment plants.
N-Chloropiperidine is a rare example of an organic chloramine. [5] Chloramine-T is often referred to as a chloramine, but it is really a salt (CH 3 C 6 H 4 SO 2 NClNa) derived from a chloramine. [6] Organic chloramines feature the NCl functional group attached to an organic substituent.
The Summary. A newly identified chemical byproduct may be present in drinking water in about a third of U.S. homes, a study found. Scientists do not yet know whether the byproduct is dangerous.
A previously unidentified chemical has been discovered in the tap water of about one-third of U.S. homes, a new study has found, and scientists are actively investigating whether it's toxic.
A 2008 study indicated that sodium hypochlorite and organic chemicals (e.g., surfactants, fragrances) contained in several household cleaning products can react to generate chlorinated volatile organic compounds (VOCs). [12] These chlorinated compounds are emitted during cleaning applications, some of which are toxic and probable human carcinogens.
The chloronitramide anion was first detected as a UV absorbance interference during monitoring of chloramine and dichloramine in 1981. [6] It was then shown to form during the decomposition of both chemicals. [6] It was shown to likely be an anion in 1990. [7]
