- •
There were significant differences in DBP formation between free and combined AAs.
- •
Tyr–Tyr–Tyr formed more TCAN than free Tyr in chlorination due to the peptide bond.
- •
The rank order for HAN control was permanganate > persulfate > hydrogen peroxide.
- •
Permanganate pre-oxidation decreased HAN but increased CF during post-chlorination.
- •
Persulfate did not increased CF and somewhat decreased HAN during post-chlorination.
