Review on removal of endocrine disrupting chemicals from water by advanced oxidation——Based on sulfate radicals
Due to the rapid development of modern industry,endocrine disrupting chemicals(EDCs)with high ecotoxicity are widely detected in the aquatic environment.In recent years,sulfate radicals-based advanced oxidation processes(SO4-·-AOPs)have been widely recognized for their high oxidative potential and effectiveness in the remediation of EDCs compared with other AOPs.In this paper,firstly,the activation mechanisms of different persulfate(PS)activation methods(e.g.,transition metal activation,carbon material activation,thermal activation,UV activation,electrochemical activation,and ultrasonic activation)and their applications in the removal of EDCs are reviewed.The advantages and limitations of each activation method are pointed out,and some effective strategies to enhance their activation performance are summarized.Secondly,the application of sulfite as a novel precursor for the generation of SO4·is presented,and the changes in toxicity of intermediates during the degradation of EDCs are emphasized.Finally,the research progress is summarized and prospected.In the future,it can be considered to expand the research of machine learning in predicting the reactivity,oxidation mechanism,generated transformation products and their toxicity of SO4·to different EDCs,so as to further enhance the practical application potential of SO4-·-AOPs.
