Abstract
The transient products formed during mineralization of 2,4-D by Fe 3+ -catalyzed hydrogen peroxide in the dark or under 350-nm UV were identified in connection with studies of these advanced oxidation processes for wastewater treatment. Ethyl acetate extracts revealed 2,4-dichlorophenol as the major product (≤15% yield) and ≤3% each of 2,4-dichlorophenyl formate, 2,4-dichloro-1-(chloromethoxy)-benzene, and 6,8-dichloro-2H-1,4-benzodioxan-3-one. The aqueous phase contained oxalic acid in dark reactions and oxalic and formic acids in photoassisted reactions, identified as their 1-propanol esters
