文摘
- •
Low-pressure UV disinfection photolyze chloramphenicol (CAP) to form halomethanes.
- •
Persulfate (PS) or combined UV/PS removed CAP, but formed halomethanes (HMs).
- •
UV and/or PS increased HM yields in post-chlorination but PS reduced TCM yields.
- •
UV increased Br-HMs and total HMs from CAP chlorination in waters rich in bromide.
- •
UV/PS changed Br incorporation and utilization factors of HMs from CAP chlorination.
