Title: | Heterogeneous photodegradation of bisphenol A with iron oxides and oxalate in aqueous solution | Authors: | Li, FB Li, XZ Li, XM Liu, TX Dong, J |
Issue Date: | 15-Jul-2007 | Source: | Journal of colloid and interface science, 15 July 2007, v. 311, no. 2, p. 481-490 | 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 | Keywords: | Bisphenol A Iron oxides Oxalic acid Photodegradation |
