文摘
- •
Phenylarsonic compounds from animal wastes easily accumulate in surface water bodies.
- •
They undergo 1O2-based self-sensitized photolysis in water under sunlight irradiation.
- •
The -AsO(OH)2 group is cleaved from the aromatic ring during their photodegradation.
- •
The photodegradation can be described by a 1O2-based “heterogeneous” kinetic model.
- •
Natural organic matter significantly inhibits photodegradation of these compounds.
