- •
Kinetic model for HOI/I2 evolution during chloramination was developed.
- •
Maximum I-DBPs formation and HOI/I2 consumption occurred at pH 8.0.
- •
I-HAcAms, once formed, could be further hydrolyzed to corresponding I-HAAs.
- •
Low-SUVA254 NOM favored I-DBPs formation compared to high-SUVA254 NOM.
- •
Reaction pathways for I-DBPs formation during chloramination were proposed.
