The formation of CNBr appears to be a complex reaction in sequential disinfection treatment of drinking water with O3 and NH2Cl. Many parallel and cross-linked pathways may lead to the formation of CNBr. In simplified system containing HCHO, NH2Cl and Br the formations of CNBr and CNCl are competitive processes. High Br favors the formation of CNBr through reactions between HCHO and bromamines, CN- and bromamines, CN- and HOBr. NHClBr may also react with HCHO, in a similar way NHBr2 does, to form CNBr. Hydrolysis reactions in the pH range of 6 to 8 used in this study were found to be negligible over 24 hours period.
