This study systematically investigates the formation of trichloronitromethane (TCNM) from 2 natural waters, 6 humic substances and 16 phenolic compounds during UV/monochloramine (UV/NH2Cl) followed by post-chloramination. Using 15N-NH2Cl as an isotope tracer, we found that 15N-TCNM accounted for 70.7-76.5% of total TCNM during UV/NH2Cl treated 2 natural waters, which was significantly higher than the proportion of 15N-TCNM in chloramination (NH2Cl alone). This is a direct evidence that NH2Cl, rather than the nitrogenous matters in waters, was t
