[Display omitted] • E-Fe 1 Ni 5 -NC-600 system exhibited satisfactory performances for TC degradation. • Synergy existed between electro- and catalytic-activation for PS activation. • Electric field accelerated the redox cycles of Fe0/Fe2+/Fe3+ and Ni0/Ni2+/Ni3+. • Both reactive species and electron-transfer process contributed to TC removal. • E-Fe 1 Ni 5 -NC-600/PS system had a low energy consumption (0.34 kWh/m3-log). The booming demand for modern medicine has led to the widespread occurrence of antibiotics in aquatic environments. The co-activation of persulfate (PS) by electrochemical and catalytic processes has now drawn increasing interests for the treatment of refractory contaminants in water. Herein, N-doped porous carbon decorated with Fe/Ni bimetallic composite catalyst (FeNi-NC) was prepared with Fe-doped Ni-MOFs as a precursor. The composite catalyst was evaluated for it performance to catalyze PS in the presence of an electric field for the destruction of tetracycline (TC). Thanks to the synergistic effect between the electrochemical and Fe 1 Ni 5 -NC-600 catalytic processes to activate PS, the E-Fe 1 Ni 5 -NC-600 system exhibited a satisfactory performance for TC degradation, attaining a 91.94 % removal within 90 min. Electric field accelerated the redox cycles of Fe0/Fe2+/Fe3+ and Ni0/Ni2+/Ni3+ to realize the sustainable catalytic activation of PS to form reactive species (OH, SO 4 −, and 1O 2) for enhanced TC degradation. Competition kinetics studies suggested OH was the dominant reactive species, and electron-transfer process also contributed to TC removal. Moreover, the E-Fe 1 Ni 5 -NC-600/PS system exhibited a low energy consumption (0.34 kWh/m3-log), wide effectiveness in the elimination of on different organic pollutants, and good applicability for real water treatment. This study provided new insights into the application of PS-based advanced oxidation process for the high-performance treatment of antibiotic-containing wastewater. [ABSTRACT FROM AUTHOR]

Various detection, analysis and remediation methods have been reported for pharmaceuticals and personal care products (PPCPs) in wastewater. In this review, the biotoxicity of PPCPs were briefly introduced. Because of PPCPs' hazardous to the environment, the enrichment and extraction methods (e.g., solid phase extraction, soxhlet extraction, supercrtical fluid extraction, and microwave assisted extraction) for PPCPs were systematically described. PPCPs analysis technologies (e.g., liquid chromatography-mass spectrometry, gas chromatograph-mass spectrometer, capillary electrophoresis, and sensors) were summarized. The removal performances and mechanisms of PPCPs through different electrochemical treatment approaches (e.g., electro-Fenton, photoelectrocatalytic degradation, and electrochemical membrane bioreactor) were critically analyzed and discussed. Finally, the concluding remarks and suggestions for future researches concerning the topic of PPCPs detection, analysis, and electrochemical treatments were proposed. This work could provide an overview for the detection/analysis techniques and electrochemical treatments of PPCPs from wastewater.
