Organic contaminants with lower Hammett constants are typically more prone to being attacked by reactive oxygen species (ROS) in advanced oxidation processes (AOPs). However, the interactions of an organic contaminant catalytic centers and participating ROS complex lack in-depth understanding. In this work, we observed abnormal phenomenon AOPs that degradation electron-rich phenolics, such as 4-methoxyphenol, acetaminophen, 4-presol, was unexpectedly slower than electron-deficient phenolics a Mn(II)/nitrilotriacetic acid/peroxymonosulfate (Mn(II)/NTA/PMS) system. The established quantitative structure-activity relationship revealed volcano-type dependence rates on pollutants. Leveraging substantial analytical techniques modeling analysis, concluded would inhibit generation both primary (Mn(III)NTA) secondary (Mn(V)NTA) high-valent manganese through complexation competition effects. Specifically, form hydrogen bond Mn(II)/NTA/PMS outer-sphere interactions, thereby reducing electrophilic reactivity PMS accept electron transfer from Mn(II)NTA, slowing down Mn(III)NTA. Furthermore, generated Mn(III)NTA is inclined react due their higher reaction rate (8314 ± 440, 6372 146, 6919 31 M
