Peracetic acid (PAA) has received increasing attention as an alternative oxidant for wastewater treatment. However, existing processes PAA activation to generate reactive species typically require external energy input (e.g., electrically and UV-mediated activation) or catalysts Co2+), inevitably treatment costs introducing potential new contaminants that necessitate additional removal. In this work, we developed a catalyst-free, self-sustaining bioelectrochemical approach within two-chamber system (BES), where cathode electrode in-situ activates using renewable biogenic electrons generated by anodic exoelectrogens Geobacter) degrading biodegradable organic matter acetic acid) in at the anode. This innovative BES-PAA technique achieved 98 % 81 removal of 2 µM sulfamethoxazole (SMX) two hours pH (cation exchange membrane) 6 (bipolar 100 μM without voltage. Mechanistic studies, including radical quenching, molecular probe validation, electron spin resonance (ESR) experiments, density functional theory (DFT) calculations, revealed SMX degradation was driven via electron-mediated OO cleavage PAA, with CH3C(O)OO• contributing 68.1 %, •OH 18.4 CH3C(O)O• 9.4 initial formation rapidly reacts produce CH3C(O)OO•. The presence common water constituents such anions Cl−, NO3−, H2PO4−) humic (HA) significantly hinders technique, whereas CO32− HCO3− ions have comparatively minor impact. Additionally, study investigated various pharmaceuticals present secondary treated municipal wastewater, attributing differences efficiency selective action research demonstrates novel method is ecologically benign, inexpensive, capable overcoming catalyst deactivation pollution issues.
