Preparations of catalysts for sulfate radicals-based advanced oxidation (SR-AOPs) are usually time-consuming and costly. This study developed a short-cut method for preparation of AOPs catalyst (MS-N3H) directly from electrolytic manganese slag. MS-N3H/PMS could effectively remove levofloxacin (LVF) from solution. Phase transformation and active sites exposure after modifications facilitated the adsorption and catalysis capacities. Both radical and non-radical pathway contributed to the degradation of LVF, in which abundant Mn and Fe on MS-N3H surface contributed to the generation of SO₄⁻, OH and O₂⁻ radicals, and lattice oxygen played a crucial role in non-radical ¹O₂ production. The MS-N3H/PMS was stable for the degradation of LVF in different water matrixes and kept high recyclability even after four recycles. This study brought underlying insights to develop novel high-efficient and easy-preparing catalysts for the degradation of recalcitrant organic pollutes.

用于基于硫酸根的高级氧化（SR-AOP）的催化剂的制备通常是耗时且昂贵的。本研究开发了一种直接从电解锰渣中制备AOPs催化剂（MS-N3H）的捷径方法。MS-N3H / PMS可以有效地从溶液中去除左氧氟沙星（LVF）。改性后的相变和活性位点暴露促进了吸附和催化能力。两个自由基和非自由基途径促成LVF的降解，其中丰富Mn和Fe在MS-N3H表面有助于SO的产生₄ ^- ，OH和O ₂ ^-的基团，和晶格氧在非起到了至关重要的作用-自由基¹ O ₂生产。MS-N3H / PMS在不同的水基质中对LVF的降解稳定，即使经过4次循环，仍保持较高的循环利用性。这项研究为开发新型高效，易于制备的难降解有机污染物降解催化剂带来了深刻见解。
