Peroxymonosulfate (PMS) mediated radical and nonradical active substances can synergistically achieve the efficient elimination of antibiotic resistance genes (ARGs). However, enhancing interface electron cycling optimizing coupling oxygen-containing intermediates to improve PMS activation kinetics remains a major challenge. Here, Co doped CeVO4 catalyst (Co-CVO) with asymmetric sites was constructed based on Ce 4f-O 2p-Co 3d gradient orbital coupling. The achieved approximately 2.51×105 copies/mL extracellular ARGs (eARGs) removal within 15 minutes, exhibited ultrahigh degradation rate (k=1.24 min-1 ). effective 4f-2p-3d precisely regulates distribution Ce-O-Co center microenvironment, while electronic structure states (especially occupancy eg ), promoting adsorption intermediates. generated by interfacial enhanced reduction reaction at site oxidation significant mineralization (83.4 %). continuous flow reactor for 10 hours significantly reduces ecological risk in actual wastewater treatment.

The removal of antibiotic-resistant bacteria (ARB) and antibiotic-resistance genes (ARGs) using sulfate anion radical (SO4•–)-based advanced oxidation processes has gained considerable attention recently. However, immense uncertainties persist in technology transfer. Particularly, the impact dichlorine (Cl2•–) generation during SO4•–-mediated disinfection on ARB/ARGs remains unclear, despite Cl2•– concentration reaching levels notably higher than those SO4•– certain SO4•–-based procedures applied to secondary effluents, hospital wastewaters, marine waters. experimental results this study reveal a detrimental effect efficiency tetracycline-resistant Escherichia coli (Tc-ARB) treatment owing generation. Through comparative investigation distinct inactivation mechanisms Tc-ARB Cl2•–- processes, encompassing various perspectives, we confirm that is less effective inducing cellular structural damage, perturbing metabolic activity, disrupting antioxidant enzyme system, damaging genetic material, viable but nonculturable state. Consequently, diminishes Importantly, indicate increases potential risk associated with dark reactivation vertical gene transfer process following disinfection. This underscores undesired role for process.
