| 英文摘要 | Oil-based drill cutting ash (OBCDA) has been used in the remediation of water and soil polluted with heavy metals. However, it has not been applied in the treatment of water polluted by antibiotics. Therefore, in this study, secondary pyrolysis OBCDA (OBDCA-sp) was employed as an efficient and environmentally friendly catalyst for peroxymonosulfate (PMS)/periodate (PI) activation to degrade tetracycline (TC). We assessed the effects of the OBDCA-sp dosage, PMS/PI concentration, and solution pH on the TC degradation process. Acidic conditions were conducive to the removal of TC from both systems (i.e., the PMS and PI systems). Under the optimal conditions, OBDCA-sp + PMS and OBDCA-sp + PI successfully degraded 92.6 and 85.8% of the TC content within 60 min, respectively. The fresh and used OBDCA-sp were assessed using a range of analytical techniques, and the possible reactive sites for PMS/PI activation were derived from the transition metals (Fe, Mn, and Co) present in OBDCA-sp. The results of scavenging experiments and electron paramagnetic resonance spectroscopy indicated that non-radicals (O-1(2)) and radicals ((OH)-O-center dot, SO4 center dot-, and O-center dot(2)-) were the main reactive oxidation species involved in the degradation of TC. Overall, the OBDCA-sp/PMS system was more favorable for the degradation of TC than the OBDCA-sp/PI system. Thus, through this study, we developed a new perspective for the utilization of solid waste resources and the novel application of advanced oxidation technologies. |
