This was followed in 2000 by the discovery of a new type ...
Explainer: The chemistry that keeps swimming pools clean and safe
网页2022年8月4日 · Chloramines can form in various ways in swimming pools. One of the simplest is the reaction of ammonia-like compounds, such as urea from swimmers, with hypochlorous acid. This leads to the formation of mono-, di- and trichloramines. Chloramine formation: R 2 NH + HOCl → R 2 NCl + H 2 O. These toxic chloramines then evaporate, producing the ...
