WebReactive nitrogen species (RNS) have long been postulated to form in chloramine systems used in water disinfection. However, the identification of these RNS and delineation of their roles in the formation of toxic disinfection by-products (DBPs) such as N-nitrosodimethylamine (NDMA) has remained elusive. WebReactive species are frequently measured using spectroscopic methods such as optical emission spectroscopy (OES), absorption spectroscopy, and laser-induced fluorescence (LIF). Although OES can be applied using basic equipment, it can only measure a limited number of types of reactive species, and analyzing the measured data can be complicated.
