Abstract: To understand the degradation of endocrine disrupting chemicals (EDCs) with existence of iron oxides and polycarboxylic acids in the natural environment, the photodegradation of bisphenol A (BPA) at the interface of iron oxides under UV illumination was conducted. Four iron oxides were prepared by a hydrothermal process and then sintered at different temperatures of 65, 280, 310, and 420¢XC named "O-65," "IO-280," "IO-310," and "IO-420," respectively. The prepared iron oxides were characterized by X-ray diffraction (XRD) and Brunauer¡VEmmett¡VTeller (BET) methods. The XRD pattern of IO-65 showed a crystal structure of lepidocrocite (£^ -FeOOH) and that of IO-420 demonstrated a crystal structure of hematite (£\-Fe?O?), while IO-280 and IO-310 have the mixed crystal structures of maghemite (£^ -Fe?O?) and hematite. The BET results revealed that the specific surface areas decreased with the increase of sintering temperature. The results demonstrated th
