- •
Low-molecular-weight organic acids have significant influence on PAHs photolysis.
- •
Chelating ability of LMWOAs with Fe are critical to their roles in Phe photolysis.
- •
Presence of oxalic and malic acids favor Phe photodegradation on Fe(III)–clay.
- •
EDTA or nitrilotriacetic acid inhibits both Fe(II) formation and Phe photolysis.

CO2− radicals involved in Phe photodegradation are supported by EPR.
