N-Nitrosodimethylamine (NDMA) formation experiments conducted in phosphate buffer demonstrated that in waters containing monochloramine, the presence of bromide ion enhanced NDMA formation at the relatively high pH values of 8 and 9 after 24 h of reaction time, which was consistent with literature r...
