Poultry manure is one of the important sources antibiotic pollution in agricultural soil and groundwater. Recently, excessive discharge goat has resulted groundwater environmental challenges negative impacts. It practical significance that such wastes can be converted into functional materials to promote resource utilization waste reduce risk contamination. In this study, Fe (Ⅱ)-loaded biochar (Fe-GMC) was prepared by pyrolyzing iron salts used activate peroxymonosulfate (PMS) for tetracycline (TC) degradation The as-prepared Fe-GMC exhibited good catalytic performance PMS activation due its porous surface rich oxygen-containing groups. Under conditions catalyst dosage 0.2 g/L, 1.0 mM, pH 3.0, TC removed 81.3% within 60 min. addition, efficiency inhibited different extents inorganic anions (HCO 3 − >Cl >NO ) water. Furthermore, quenching experiments, electron paramagnetic resonance (EPR) X-ray photoelectron spectroscopy (XPS) spectra analysis indicated generation hydroxyl radicals ( • OH) responsible degradation. Particularly, produces a strong oxidizing agent. This study provides an efficient environmentally friendly catalyst, which offers new theoretical basis water remediation.
