“…Advanced oxidation processes (AOPs) were first proposed for potable water treatment in the 1980s [1,2], which are defined as the oxidation processes involving the generation of hydroxyl radicals (OH·) in sufficient quantity to effect water purification. Later, the AOP concept has been extended to the oxidative processes with sulfate radicals (SO 4 have too short half-life (on the order of microseconds), so that the required detention times for disinfection are prohibitive due to extremely low radical concentrations [5].…”

“…29,[34][35][36][37][38][39] For example, ozone has been employed as a powerful drinking-water disinfectant and oxidant. 34,35,40 On the other hand, when the ozone level in an atmosphere exceeds a certain threshold value, the exposure to this gas becomes hazardous to human health and can cause serious health problems (e.g. headache, burning eyes, respiratory irritation and lung damage).…”

“…In water solution, ozone can react with organic compounds via: (1) ble bonds (CϭC, CϭN, NϭN); and (2) in situ generation of hydroxyl radicals [38], reactive species formed during ozone decomposition specially at high pH [39] (note that such specific pH conditions were not employed in our experimental setup as described in Experimental section). Therefore, the formation of the oxidation product 2 is proposed to involve an initial 1,3-dipolar cycloaddition of ozone, an electrophilic specie, towards the C11a-C12 double-bond of 1 to yield an unstable ozonide intermediate [40], which in fact was not detected during the ESI(ϩ)-MS monitoring (Scheme 4).…”
