Peroxymonosulfate (PMS) was employed as an activator of ozone (O3) to degrade non-steroidal anti-inflammatory drugs (NSAIDs) (aspirin (ASA) and phenacetin (PNT)) in study. The combination of PMS in O3 system promoted the O3 decomposition and NSAIDs removal significantly. O3 molecule, hydroxyl radical (OH) and sulfate radical (SO4-) were responsible for the removal of target pollutants in O3/PMS system. The second-rate constants between O3, OH and SO4- with ASA were determined to be 7.32, 4.18… Expand
