    Poultry manure is one of the important sources of antibiotic pollution in agricultural soil and groundwater. Recently, this excessive discharge of goat manure has resulted in groundwater environmental challenges and negative impacts. It is of practical significance that such wastes can be converted into functional materials to realize the resource utilization of waste and reduce the risk of antibiotic contamination.In this study, the Fe(Ⅱ) loaded goat manure biochar (Fe-GMC) was prepared by pyrolyzing goat manure and iron salts and used to activate peroxymonosulfate (PMS) for Tetracycline (TC) degradation in groundwater. The as-prepared Fe-GMC exhibited good catalytic performance for PMS activation due to its surface is porous and rich in oxygen-containing groups. Under the conditions of catalyst dosage of 0.2 g/L, PMS dosage of 1.0 mM, and pH of 3.0, the TC was removed 81.3% within 60 min. Besides, the TC degradation efficiency was different extents inhibited by inorganic anions (HCO3 ->Cl ->NO3 -) in water. Furthermore, The quenching experiments and electron paramagnetic resonance (EPR) experiments analysis, and X-ray photoelectron spectroscopy (XPS) spectra analysis indicated that the generation of the hydroxyl radicals ( • OH) was responsible for TC degradation. Particularly, the Fe-GMC produces a strong oxidizing agent. This study provides an efficient and environmentally friendly tetracycline degradation catalyst, which a new theoretical basis for water environmental remediation.
