	abstract = {In this work, the different selectivity of SO4{\textbullet}- and {\textbullet}OH towards municipal solid waste incineration leachates (MSWILs) was studied by a comparative study of UV/persulfate (PS) and UV/H2O2. Results showed SO4{\textbullet}- preferentially mineralized carbon atoms of higher average oxidation state, while {\textbullet}OH showed a two-stage mechanism of partial oxidation and mineralization successively. Electron spin resonance (ESR) analysis showed SO4{\textbullet}- had superior selectivity towards MSWILs than {\textbullet}OH, and Fe(II) would significantly affect the selectivity via forming Fe-MSWILs complex. As the consequence, Fe(II) showed slightly negative effect on UV/PS, but greatly enhanced the performance of UV/H2O2/Fe(II). High concentration of Cl- affected the degradation of non-fluorescent substances by UV/PS, while SO42- and NO3- showed no effect. In contrast, anions showed no effect on UV/H2O2. In addition, {\textbullet}OH preferentially attacked large molecules, but SO4{\textbullet}- showed no selectivity. This study further revealed the selectivity of SO4{\textbullet}- and {\textbullet}OH in the treatment of hypersaline wastewater, and provided theoretical support for the development of targeted technology.},
