Résumé

Recently, the application of cheap, easily available biochar (BC) in advanced oxidation processes (AOPs) has received widespread attention. However, it is still a challenge to seek effective modification methods to prepare BC with high catalytic performance. In this study, a novel and environmentally friendly graphitized BC (WGBC) derived from wood chip was prepared, which exhibited excellent performance towards persulfate (PS) activation for sulfamethoxazole (SMX) removal as compared to original BC. Series characterizations confirmed that such improved catalytic performance was attributed to the well-established graphitic carbon structure and surface functionalized CO group. Free radical quenching and electron paramagnetic resonance (EPR) experiments qualitatively demonstrated that SO
