The Fe-Mn oxides composite prepared by a chemical co-precipitation method was used as a heterogenous peroxydisulfate catalyst for the decomposition of aniline. This study investigated the mechanism of aniline degradation by PDS activated with catalyst. Reactive species resulting in the degradation of aniline was investigated via radical quenching experiments with different scavengers, including methanol, tert-butyl alcohol, EDTA and sodium azide. Based on the experiments made here, it is speculated that the predominant reactive species responsible for the degradation of aniline may be holes and singlet molecular oxygen rather than SO₄^·− and ·OH radicals. The degradation of compounds in catalyst/peroxydisulfate system was put forward. The three possible intermediates were speculated by high performance liquid chromatography-mass spectrometry, and two possible degradation pathways were proposed.

通过化学共沉淀法制备的 Fe-Mn 氧化物复合材料用作多相过二硫酸盐催化剂用于苯胺的分解。本研究研究了用催化剂活化的 PDS 降解苯胺的机制。通过使用不同清除剂（包括甲醇、叔丁醇、EDTA 和叠氮化钠）进行自由基淬灭实验，研究了导致苯胺降解的反应性物质。根据这里进行的实验，推测负责苯胺降解的主要反应物种可能是空穴和单线态分子氧而不是 SO ₄ ^·-和·OH自由基。提出了催化剂/过硫酸盐体系中化合物的降解。通过高效液相色谱-质谱法推测了三种可能的中间体，并提出了两种可能的降解途径。
