By means of characterization, this research investigated the phase structure, surface morphology, reducibility, surface element composition, and valence of the catalyst before and after reuse. The effects of catalyst dosage and pH on the removal efficiency of BPA were also investigated. Five reuse experiments were carried out to investigate the reusability of the catalyst. In addition, this research delved into the changes of pH value, hydroxyl radical concentration, and ultraviolet-visible spectra of BPA in CWPO reaction system. The possible intermediate products were analyzed by gas chromatography-mass spectrometry (GC-MS). The catalytic mechanism and degradation pathway were also discussed. The results showed that after reaction of 65 min, the removal of BPA and total organic carbon (TOC) could reach 87.6% and 77.9%, respectively. The catalyst showed strong pH adaptability and had high removal efficiency of BPA in the range of pH 1.6\u20137.9. After five reuses, the removal of BPA remained above 86.7%, with the structure of the catalyst remaining stable to a large extent. With the reaction proceeding, the pH value of the reaction solution increased, the concentration of OH radicals decreased, and the ultraviolet-visible spectrum of BPA shifted to the short wavelength direction, that is, the blue shift direction. The catalysts degraded BPA rapidly in CWPO reaction system and the C\u2013C bond or O\u2013H bond in BPA could be destroyed in a very short time. Also, there may have been two main degradation paths of phenol and ketone.<\/jats:p>","DOI":"10.3390\/ijerph16234675","type":"journal-article","created":{"date-parts":[[2019,11,25]],"date-time":"2019-11-25T03:10:00Z","timestamp":1574651400000},"page":"4675","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Degradation of Bisphenol A by CeCu Oxide Catalyst in Catalytic Wet Peroxide Oxidation: Efficiency, Stability, and Mechanism"],"prefix":"10.3390","volume":"16","author":[{"given":"Zhaojie","family":"Jiao","sequence":"first","affiliation":[{"name":"Engineering Research Center for Waste Oil Recovery Technology and Equipment of Ministry of Education, Chongqing Technology and Business University, Chongqing 400067, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ligong","family":"Chen","sequence":"additional","affiliation":[{"name":"Engineering Research Center for Waste Oil Recovery Technology and Equipment of Ministry of Education, Chongqing Technology and Business University, Chongqing 400067, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guilin","family":"Zhou","sequence":"additional","affiliation":[{"name":"Engineering Research Center for Waste Oil Recovery Technology and Equipment of Ministry of Education, Chongqing Technology and Business University, Chongqing 400067, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haifeng","family":"Gong","sequence":"additional","affiliation":[{"name":"Engineering Research Center for Waste Oil Recovery Technology and Equipment of Ministry of Education, Chongqing Technology and Business University, Chongqing 400067, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianming","family":"Zhang","sequence":"additional","affiliation":[{"name":"Engineering Research Center for Waste Oil Recovery Technology and Equipment of Ministry of Education, Chongqing Technology and Business University, Chongqing 400067, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunqi","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Heavy Oil Processing, China University of Petroleum (East China), Qingdao 266580, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Gao","sequence":"additional","affiliation":[{"name":"National Research Base of Intelligent Manufacturing Service, Chongqing Technology and Business University, Chongqing 400067, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"214","DOI":"10.1016\/j.chemosphere.2018.02.179","article-title":"Bisphenols: Application, occurrence, safety, and biodegradation mediated by bacterial communities in wastewater treatment plants and rivers","volume":"201","year":"2018","journal-title":"Chemosphere"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1016\/j.tox.2017.06.007","article-title":"Anti-androgenic mechanisms of Bisphenol A involve androgen receptor signaling pathway","volume":"387","author":"Wang","year":"2017","journal-title":"Toxicology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"885","DOI":"10.1016\/j.chemosphere.2016.10.121","article-title":"Adsorptive removal of bisphenol A (BPA) from aqueous solution: A review","volume":"168","author":"Bhatnagar","year":"2017","journal-title":"Chemosphere"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.cattod.2016.11.009","article-title":"Enhanced photo-degradation of bisphenol pollutants onto gold-modified photocatalysts","volume":"284","author":"Cojocaru","year":"2017","journal-title":"Catal.
