Recent advances in H 2 O 2-base d advance d oxidation processes for removal of antibiotics from wastewater

As important emerging contaminants, antibiotics have caused potential hazards to the ecological environ-ment and human health due to their extensive production and consumption. Among various techniques for removing antibiotics from wastewater, H2O2-based advanced oxidation processes (AOPs) have received increasing attention due to their fast reaction rate and strong oxidation capability. Hence this review crit-ically discusses: (i) Recent research progress of AOPs with the addition of H2O2 for antibiotics removal through different methods of H2O2 activation; (ii) recent advances in AOPs that can in-situ generate and activate H2O2 for antibiotics removal; (iii) H2O2-based AOPs as a combination with other techniques for the degradation and mineralization of antibiotics in wastewater. Future perspectives about H2O2-based AOPs are also presented to grasp the future research trend in the area.(c) 2022 Published by Elsevier B.V. on behalf of Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

Automated summary

This review critically discusses the application of H2O2-based advanced oxidation processes (AOPs) for the removal of antibiotics from wastewater. The article presents recent research progress in the combination of H2O2 with AOPs through different reaction mechanisms, recent advances in AOPs that can generate and activate H2O2 in situ, and the use of H2O2-based AOPs in combination with other techniques for the degradation and mineralization of antibiotics. Future research trends in H2O2-based AOPs are also discussed.
