Recently, nitrogen-doped biochar (NBC) has attracted a great deal of attention in the field advanced oxidation processes (AOPs) for treatment various pollutants. However, effect nitrogen doping method on catalyst efficiency NBC not been fully understood. In this study, was prepared using two different methods: carbonization urea mixed with maize straw (NBC1) and pristine obtained from (NBC2). Catalytic degradation tetracycline (TC) presence peroxydisulfate (PDS) examined, process factors reaction mechanism were explored. Characterizations revealed that NBC1 had higher content (6.86 %) carbon defects compared to NBC2. Under optimum conditions 0.4 g L−1, PDS 3 mM, TC 15 mg solution pH 4.6, reached over 86.55 % within 120 min, which than NBC2 (57.10 %). Moreover, catalytic system showed resistance anions dissolved organic matter, by remained 82.47 after secondary carbonization. Radical quenching electron spin resonance spectroscopy verified co-existence ·OH, SO4·−, O2·−, 1O2 system, made significant contribution degradation. More importantly, quantitative structure-activity relationships (QSAR) density functional theory (DFT) calculations displayed graphitic N, as primary active site, played an important role activation This work provides evidence preparation efficient biochar, elucidation mechanism, its feasibility wastewater treatment.
