The rapid and selective peroxymonosulfate (PMS) induced transformation of H₁-antihistamines cetirizine (CET) and diphenhydramine (DPH) can be influenced by the presence of common organic and inorganic water constituents. Presence of HCO₃^– and/or CO₃^2–, which often exhibit powerful inhibition on the advanced oxidation processes (AOPs), can enhance the PMS mediated transformation of CET/DPH. The observed promotion is demonstrated by the changed solution pH through detailed kinetic studies. The impact of halide ions is remarkable, with I^– inhibiting the process through consumption of PMS, while Cl^– increases slightly the transformation kinetics through the formation and subsequent reactions of HOCl. The CET/DPH degradation in the Br^–/PMS system is influenced by the generation of reactive species such as HOBr which leads to different reaction pathways as compared to PMS alone. The results demonstrated the performance of PMS can be tailored through varying the experimental parameters. In addition, the presence of model organic constituents found in water, e.g., humic acid, phenol, pyridine or sorbate, has a minimal effect on the PMS mediated oxidation processes, highlighting the strong application potential of PMS in water treatment.

H _1-抗组胺西替利嗪（CET）和苯海拉明（DPH）的快速和选择性过氧一硫酸盐（PMS）诱导的转化会受到常见有机和无机水成分的影响。HCO ₃ ^–和/或CO ₃ ^{2 –的}存在通常对高级氧化过程（AOP）表现出强大的抑制作用，可以增强PMS介导的CET / DPH转化。通过详细的动力学研究，观察到的促进作用是由溶液pH值的变化证明的。卤离子的影响非常显着，其中I ^–通过消耗PMS抑制了这一过程，而Cl ^–通过HOCl的形成和随后的反应稍微增加了转化动力学。在BR中的CET / DPH降解^- / PMS系统是由反应性物质如次溴酸，这导致不同的反应途径与单独相比PMS的产生的影响。结果表明，可以通过更改实验参数来调整PMS的性能。另外，在水中发现的模型有机成分（例如腐殖酸，苯酚，吡啶或山梨酸酯）的存在对PMS介导的氧化过程影响最小，突出了PMS在水处理中的强大应用潜力。
