文摘
- •
Halide ions pose special promotion in the photolysis of sulfamethazine.
- •
Photolytic rate of sulfamethazine is higher in seawater than that in freshwater.
- •
Triplet-excited sulfamethazine can react with Cl− and Br− ions.
- •
Halogenated intermediates of sulfamethazine were formed in seawater.
- •
Halogenation reaction can be predicted based on oxidation potential.
