Experimental of ARB inactivation and ARGs elimination via E/CPFS@ACFs/PMS system

Antibiotic resistance genes (ARGs) in wastewater treatment plant (WWTP) secondary effluent exhibit size-fractionated characteristics, which conventional processes struggle to remove effectively. This study systematically investigates the removal of ARGs via electrochemically activated peroxymonosulfate (PMS) and further elucidates the size-dependent removal efficiency and bacterial stress response mechanisms triggered by this process. A Co/P co-doped FeS2-modified activated carbon fiber composite cathode (CPFS@ACFs) was developed for this purpose.
