“…In the recent years, a great scientific interest is being placed on the sulfate radical‐based AOPs due to their high efficiency in degrading a wide range of recalcitrant microcontaminants in aqueous matrices, including pharmaceuticals (Guo, Ke, Gao, Liu, & Cheng, ; Michael‐Kordatou et al, ; Tan et al, ). Persulfate radicals can be produced by the activation of persulfate, peroxymonosulfate, potassium persulfate, and ammonium persulfate anion (Ao & Liu, ) by various methods, such as heat (Johnson, Tratnyek, & Johnson, ), ultrasonic (Hori, Nagano, Murayama, Koike, & Kutsuna, ), and UV (Mahdi‐Ahmed & Chiron, ).…”
