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.

DBP和DEHP的光降解历程相似，主要反应途径是OH自由基提取烷基上与羧基相连的α-H原子，然后被氧化生成醇衍生物，再分解成为酞酸和二醇，酞酸经历开环和进一步脱羧，二醇可以被氧化成为低级烷基羧酸，直至矿化。
