Peroxyacetic acid (PAA)-based advanced oxidation processes (AOPs) have attracted much attention in wastewater treatment by reason of high selectivity, long half-life reactive oxygen species (ROS), and wider applicability. In this study, cobalt ferrite (CoFe2O4) was applied to activate PAA for the removal ofloxacin (OFX). The degradation OFX could reach 83.0% via CoFe2O4/PAA system under neutral conditions. low concentration co-existing anions organic matter displayed negligible influence on removal. contributions hydroxyl radicals (·OH), (R-O·), other were systematically evaluated. Organic (especially CH3C(O)OO·) singlet (1O2) verified be main leading destruction. Co(II)/Co(III) redox cycle occurring surface CoFe2O4 played a significant role activation. catalytic performance remained above 80% after five cycles. Furthermore, ecotoxicity reduced with system. This study will facilitate further research development as new strategy treatment.

This study established an efficient coupled activation persulfate (PMS) process with a bimetallic modified biochar (MBC)-loaded cathode (MBC@CF) as the main body to remove tetracycline (TC) by electric field-enhanced catalytic cathodic of PMS (E-MBC@CF-PMS). The synergistic effect electrocatalytic co-activation in E-MBC@CF-PMS system (5.54) was two three times higher than electrically activated (2.39) / electro-catalytic (2.03) systems. fundamental reason is that presence field enhances at sites like C=O and Metal-N-C (M-N-C) on surface makes it easier for vital element Mn+ ligand structure regenerate. 1O2 generated during electron transfer demonstrated dominate removal pollutants using free radical quenching spin resonance. offers fresh idea encourage effective practical PMS.

Multiphase catalysts with wide pH, high environmental adaptability, and activity are urgently needed for the water's contaminants to break down. In this study, biomass waste bamboo leaves were used as carbon source activated by KOH further increase active sites (the adsorption capacity was 8.06 times that of unactivated material) loaded cobalt ferrite composite catalyst CoFe2O4@PBCX, which could effectively activate PMS realize degradation BPA. The CoFe2O4@PBCX + system demonstrated remarkable BPA across a broad starting pH range (3-11), 100% removal achieved in 9 min at pH=11.CoFe2O4@PBCX excellent performance under salinity conditions (200 mM). toxicity its oxidation intermediates predicted ECOSAR model, proved eventually degraded into non-toxic products. bisphenol device, no deactivation observed after 14 h, 80% maintained 40 h. This study showed synthesized is highly efficient activation catalyst, has potential low cost, efficiency, ecological friendliness practical wastewater treatment.
