文摘
- •
The degradation order observed for LP-UV/H2O2 was mecoprop > metaldehyde > clopyralid.
- •
The same degradation order was observed for the reaction with the OH-radicals.
- •
Clopyralid exhibited the largest enhancement in kinetics with H2O2 addition.
- •
Mecoprop produced one photolysis product and smaller ones from OH-radical attack.
- •
Clopyralid and metaldehyde produced mainly hydroxylated products.
