A novel singlet oxygen involved peroxymonosulfate activation mechanism for degradation of ofloxacin and phenol in water

This study proposed a new and previously unconsidered reaction mechanism in the activation of peroxymonosulfate. We report that singlet oxygen (O-1(2)) rather than (OH)-O-center dot or SO4 center dot- was the dominant reactive oxygen species towards the efficient degradation of ofloxacin and phenol, demonstrating a promising application in real wastewater treatment.
