Corn straw biochar (Y-BC) was prepared by high-temperature pyrolysis method and its structure and morphology properties were characterized with a series of analytical techniques. The effects of initial pH and co-existing ions on tetracycline (TC) removal by Y-BC activated two types of persulfates: peroxydisulfate (PDS) and peroxymonosulfate (PMS) were systematically compared. The results showed that Y-BC activated PDS system could effectively remove TC under acidic and neutral conditions (pH=3~7), and TC removal efficiency was between 69.0% to 75.7% in 60min, while alkaline conditions (pH=9~11) TC removal efficiency reduced to 47.8%~48.4%. In contrast, the Y-BC-activated PMS system demonstrated a broad pH range for TC removal, and TC removal efficiency stabilized at 80.9%~86.8% at initial pH 3~11. The Cl- and NO3- anions exhibited negligible effects on both activated persulfate systems. Meanwhile, HCO3- showed an inhibitory effect on TC removal by the Y-BC-activated PDS system while promoting the effect by the Y-BC-activated PMS system. TC removal efficiency decreased by 7.6% and increased by 5.1% with Y-BC-activated PDS and PMS, respectively. Combined the results of X-ray photoelectron spectroscopy, quenching experiments, and electron paramagnetic resonance analysis, it was deduced that the primary active sites for Y-BC activated PDS system were defect structures, and TC degradation was mainly through singlet oxygen (1O2) generation and electron transfer mechanisms. Conversely, functional groups served as key active sites for the Y-BC-activated PMS system, and TC degradation was primarily via hydroxyl radical (·OH) formation.
