DBP and DEHP have the similar photodegradation mechanism. The predominant pathway for DBP and DEHP photodegradation in the Fe -oxalate complexes system is hydroxyl radical extracting H atom in α-position of the aliphatic chain close to the carboxyl group followed by oxidation to produce alcoholized derivatives ROH. ROH then breaks down to phthalic acid and dialcohol that will be further oxidized up to mineralization.
