Photo-Fenton-like degradation of bisphenol A by persulfate and solar irradiation

A comprehensive review on BPA degradation by heterogeneous Fenton-like processes

“…However, still many electro-Fenton processes fail to perform efficiently at neutral pH. Khandarkhaeva et al (2019) reported an interesting phenomenon of BPA degradation by a Fenton-like process in a real wastewater matrix. Although the study has been carried out with homogeneous Fenton catalyst, the features pointed out by the authors may be helpful for heterogeneous Fenton catalysts also.…”

Environmental persistence, detection, and mitigation of endocrine disrupting contaminants in wastewater treatment plants – a review with a focus on tertiary treatment technologies

“…Another study assessed the degradation of BPA from synthetic solutions by a photo-Fenton degradation process using persulfate (PS) and Fe 2+ . 113 The authors found that using PS and Fe 2+ in a solar-driven process was the most efficient approach compared to others. A complete degradation was achieved after 5 min using a 30 W lamp and PS/BPA ratio of 20.…”

“…The optimal conditions (pH = 3, BPA concentration = 25 mg/L, H 2 O 2 concentration = 350 mg/L) allowed a BPA degradation of 77.4% and mineralization of 38.2%. Another study assessed the degradation of BPA from synthetic solutions by photo-Fenton degradation process using persulfate (PS) and Fe 2+(113). The authors found that using PS and Fe 2+ in a solar-driven process was the most efficient approach compared to others.…”

Removal of bisphenol A from acidic sulfate medium and urban wastewater using persulfate activated with electroregenerated Fe2+

“…PS activation consists in its conversion into sulfate radical anion (SO4 •− ). Ozone (Yang et al, 2016), H 2O2/Fe 2+ (Khandarkhaeva et al, 2019), H2O2/Fe3O4 (Xu et al, 2019), H2O2/zero valent iron (Girit et al, 2015;Wu et al, 2020), Fe3O4-α-MnO2 (Dong et al, 2019) and Fe 2+ (Jiang et al, 2013;Kang et al, 2018) behave as effective activators. Reaction (1) accounts for the production of SO4 •− from PS and Fe 2+ .…”
